Comma Rules That Get Tested

Most ACT English comma questions test three patterns: unnecessary commas, missing commas around nonessential info, and comma splices.
  • Never place a single comma between a subject and its verb (e.g., 'The dog, ran' is wrong).
  • Nonessential clauses/appositives need commas on BOTH sides: 'My brother, a doctor, called.'
  • Essential (restrictive) clauses take NO commas: 'The book that I lent you is overdue.'
  • A comma splice (two independent clauses joined only by a comma) is always wrong — use a period, semicolon, or conjunction instead.
  • Never use a comma before a single coordinating conjunction joining two words or phrases (only before one joining two independent clauses).
  • Introductory phrases of 4+ words are usually followed by a comma.

Semicolons, Colons, and Dashes

These three punctuation marks are ACT favorites because students often use them interchangeably when they shouldn't be.
  • A semicolon joins two independent clauses (each side must be a complete sentence).
  • A colon follows a complete independent clause and introduces a list, explanation, or quotation.
  • Never put a colon directly after a verb or preposition (e.g., NOT 'The ingredients are: eggs, milk.').
  • A pair of dashes can replace a pair of commas to set off nonessential information — but don't mix one dash and one comma.
  • Semicolons can also separate items in a complex list that already contains commas.
  • If you can't identify two independent clauses, a semicolon is wrong.

Redundancy and Wordiness (Concision)

When answer choices differ mainly in length, the ACT usually rewards the shortest option that preserves meaning and grammar.
  • Eliminate phrases that repeat an idea already stated, like 'combine together' or 'past history.'
  • Prefer active voice and direct phrasing over wordy constructions like 'due to the fact that' (use 'because').
  • Watch for answer choices that just add extra words without adding meaning — these are usually wrong.
  • 'The reason why is because' is always redundant; choose 'because' alone.
  • Concise is not always correct — never cut information the passage needs for clarity.
  • Check whether a shorter option changes the meaning; if not, pick it.

Subject-Verb and Pronoun Agreement

Agreement errors are hidden by long prepositional phrases or lists inserted between the subject and the verb.
  • Cross out prepositional phrases between subject and verb to find the true subject: 'The list of items (is/are) long' → 'list ... is'.
  • Collective nouns (team, group, family) usually take singular verbs on the ACT.
  • A pronoun must agree in number with its antecedent: 'Each student must bring their (wrong) → his or her/their own pencil' depends on style rules given.
  • Watch for vague pronouns with no clear antecedent — the ACT will flag ambiguous 'it' or 'they.'
  • Compound subjects joined by 'and' are plural; joined by 'or/nor' agree with the nearer subject.
  • Indefinite pronouns like 'each,' 'everyone,' and 'neither' are singular.

Rhetorical Skills: Transitions, Order, and Purpose

About a quarter of English questions ask about the passage as a whole rather than grammar — these test logic and organization.
  • Transition words must match the logical relationship: contrast (however, although), addition (furthermore), cause/effect (therefore, as a result).
  • 'ADD/DELETE' questions require you to check whether the sentence supports the paragraph's main point, not just whether it's interesting.
  • Sentence-order questions rely on pronoun references and time clues to find the correct sequence.
  • 'Which choice best accomplishes the writer's goal' questions require rereading the stated goal, not just picking the best-sounding sentence.
  • Conclusion questions need a sentence that wraps up the paragraph's specific point, not a generic summary.
  • Always check one sentence before and after the underlined portion for context.

Apostrophes and Word Choice Pairs

The ACT frequently tests commonly confused words and possessive forms in the same passage.
  • 'Its' is possessive; 'it's' means 'it is' — never confuse them.
  • 'Their' is possessive, 'there' is a location, 'they're' means 'they are.'
  • Plural possessive nouns ending in -s take only an apostrophe: 'the students' books.'
  • 'Affect' is usually a verb (to influence); 'effect' is usually a noun (a result).
  • 'Then' refers to time/sequence; 'than' is used for comparisons.
  • Singular possessive nouns take apostrophe + s, even if the noun ends in s: 'James's car.'
Choosing the most 'formal-sounding' answer, not the grammatically correct or most concise one.
Adding a comma wherever you would naturally pause when reading aloud, rather than following a comma rule.
Answering rhetorical 'writer's goal' questions based on general quality of writing, not the stated goal.
Fixing only the underlined error and ignoring how the sentence fits the surrounding paragraph.

Backsolving and Plugging In Answers

When a question asks for a specific numeric value and gives answer choices, working backward from the choices is often faster than solving algebraically.
  • Start with choice (C) or (B) — the middle value — since answers are usually ordered numerically, so you can adjust up or down.
  • Plug the choice back into the original word problem, not into a derived equation.
  • Backsolving is fastest for problems involving one variable and multiple steps of arithmetic.
  • Avoid backsolving on problems asking for an expression or a variable in terms of another variable.
  • Combine backsolving with estimation to eliminate 2-3 choices immediately.
  • For 'least/greatest possible value' questions, test the extreme answer choices first.

Plugging In Numbers for Variables

For problems with variables in both the question and the answer choices, substituting simple numbers avoids abstract algebra errors.
  • Choose easy, non-trivial numbers like 2 or 3 — avoid 0 and 1, which can make multiple answers look correct.
  • Compute the target value using your chosen number(s) before checking answer choices.
  • Plug the same number(s) into every answer choice and eliminate any that don't match your target.
  • If two answers match, pick a different set of numbers to break the tie.
  • This method works especially well on percent, ratio, and 'in terms of' problems.
  • For geometry, picking numbers for side lengths can simplify area/perimeter comparisons.

Key Geometry Formulas

The ACT math section leans heavily on a small set of geometry formulas that appear across many question types.
  • Area of a triangle: (1/2) × base × height; area of a circle: πr²; circumference: 2πr.
  • Pythagorean theorem: a² + b² = c², used constantly in right-triangle and distance problems.
  • Special right triangles: 45-45-90 (sides x, x, x√2) and 30-60-90 (sides x, x√3, 2x) save time versus the Pythagorean theorem.
  • Sum of interior angles of a polygon: (n − 2) × 180°.
  • Slope formula: (y₂ − y₁)/(x₂ − x₁); slope-intercept form: y = mx + b.
  • Distance formula: √[(x₂−x₁)² + (y₂−y₁)²], derived directly from the Pythagorean theorem.

Algebra and Function Manipulation

Function notation and systems of equations questions reward recognizing structure quickly rather than brute-force solving.
  • f(x) notation just means 'plug x into the function' — evaluate step by step, innermost operation first.
  • For systems of equations, use substitution when one variable is already isolated; use elimination when coefficients line up.
  • A quadratic in the form ax² + bx + c = 0 can often be solved faster by factoring than by the quadratic formula.
  • When a graph question gives f(x) and asks about f(x) + k or f(x − h), remember: +k shifts up, −h shifts right.
  • Inequalities flip direction only when multiplying or dividing both sides by a negative number.
  • For 'solve for x in terms of y' questions, isolate x using standard algebra, then match the answer format given.

Calculator Strategy and Time Management

A calculator can speed up arithmetic but can also cost time if used on problems better solved with reasoning.
  • Not every problem requires a calculator — number-sense and logic problems are often faster by hand.
  • Use the calculator to check answers after solving algebraically, not as your primary problem-solving tool.
  • Store useful values (like π or a computed ratio) in calculator memory for multi-step problems.
  • For probability and combinatorics, know factorial and combination functions if your calculator supports them.
  • On graphing questions, you can graph both sides of an equation and find intersection points to solve.
  • Convert fractions to decimals only when needed for comparison — exact fractions avoid rounding errors.

Statistics, Probability, and Data Interpretation

The ACT tests basic statistics and probability concepts, often embedded in tables, graphs, or word problems.
  • Mean = sum of values ÷ number of values; median is the middle value when data is ordered.
  • Probability = (favorable outcomes) ÷ (total possible outcomes), always between 0 and 1.
  • For independent events, multiply individual probabilities: P(A and B) = P(A) × P(B).
  • Range = maximum − minimum; a single outlier affects the mean far more than the median.
  • When reading tables/graphs, check the axis labels and units before selecting a value.
  • Weighted averages require multiplying each value by its weight (frequency) and dividing by the total weight.
Solving with full algebra when plugging in numbers or backsolving would be faster and less error-prone.
Choosing 0 or 1 when plugging in numbers, which can make several answer choices appear correct.
Forgetting to flip an inequality sign when multiplying or dividing by a negative number.
Misreading a graph's scale or units, leading to an answer that's off by a factor of 10 or more.

Passage Mapping Instead of Full Reading

With only about 8-9 minutes per passage including questions, skimming for structure beats reading every word closely.
  • Read the first and last sentence of each paragraph carefully; skim the middle for supporting detail.
  • Jot a 3-5 word margin note capturing each paragraph's main idea as you go.
  • Note where the author's opinion or a turning point ('however,' 'but,' 'in contrast') appears — these are common question targets.
  • Underline or mentally flag proper nouns, dates, and numbers since detail questions often ask about them.
  • Don't try to memorize the passage — build a mental map you can return to using line references.
  • Spend no more than 3-4 minutes reading before moving to the questions.

Order of Passages and Question Triage

You control the order you tackle the four passages, and picking wisely protects your overall score.
  • Passage order rotates (Literary Narrative, Social Science, Humanities, Natural Science) but difficulty varies by test-taker strength, not fixed difficulty.
  • Do your strongest passage type first to bank points and build confidence/time cushion.
  • Within a passage, answer line-reference and detail questions before big-picture/inference questions, since they're faster to locate.
  • If a question stumps you after ~20 seconds of rereading, mark it and move on — return only if time remains.
  • Never leave a question blank on the ACT — there's no penalty for guessing, so always fill in an answer.
  • Save the hardest passage type for last so a time crunch affects it, not your strongest section.

Using Line References and Context

Most reading questions point you to a specific location — using that window efficiently is the core reading skill tested.
  • Always reread a few lines before AND after the cited line reference — the answer is rarely only in the exact line quoted.
  • For vocabulary-in-context questions, plug your own word into the sentence before looking at answer choices.
  • Watch for words that have a common meaning and a less common, more precise meaning — the ACT usually tests the less common one.
  • 'According to the passage' questions require textual proof, not outside knowledge or assumptions.
  • 'It can be reasonably inferred' questions still require direct textual support — inference is a small logical step, not a guess.
  • When two answers seem right, choose the one most directly supported by the text, not the one that sounds smartest.

Author's Purpose and Tone

Many big-picture questions ask why the author included something or how they feel about the topic.
  • Identify whether the overall tone is objective/informative, critical, or admiring within the first two paragraphs.
  • 'Why did the author include paragraph X' questions test function, not content — ask what job the paragraph does.
  • Watch for shifts in tone signaled by contrast words; the tone before and after a shift may differ.
  • Rhetorical questions and figurative language in Literary Narrative passages often reveal the narrator's attitude.
  • In paired-passage sets, compare each author's stance on the same issue — questions often ask how they'd respond to each other.
  • Avoid choices that describe an extreme tone (e.g., 'furious,' 'ecstatic') unless the text clearly supports that intensity.

Eliminating Wrong Answer Patterns

ACT Reading wrong answers follow predictable patterns that can be spotted and eliminated quickly.
  • Eliminate answers that are true statements but don't answer the specific question asked (out of scope).
  • Eliminate extreme language ('always,' 'never,' 'completely') unless the passage explicitly supports it.
  • Eliminate answers that reverse a relationship stated in the passage (e.g., swapping cause and effect).
  • Eliminate 'half-right' answers that start correctly but include one incorrect detail.
  • Eliminate answers that bring in outside knowledge not stated in the passage, even if factually true.
  • The correct answer is usually a restatement of the text in different words, not new information.
Rereading the entire passage from scratch to answer each question instead of using line references.
Picking an answer because it sounds sophisticated rather than because the text supports it.
Confusing a detail question (needs proof from the text) with an inference question (needs a small logical step).
Getting stuck on a hard vocabulary-in-context question instead of substituting your own word first.

The Three Passage Types

ACT Science has three recurring passage formats, and knowing which one you're facing tells you how to attack it.
  • Data Representation passages present graphs/tables and ask you to read and interpret trends directly.
  • Research Summaries describe one or more experiments and ask about design, variables, and results.
  • Conflicting Viewpoints presents 2-3 scientists' differing hypotheses about the same phenomenon and asks you to compare them.
  • Data Representation and Research Summaries questions rarely require outside science knowledge — the answer is in the figures.
  • Conflicting Viewpoints requires careful reading since there's more text and less data to scan.
  • Identify the passage type in the first few seconds by scanning for graphs/tables versus paragraphs of viewpoints.

Reading Graphs and Tables Efficiently

Most Science questions can be answered without reading the passage text at all — just the figures.
  • Identify the independent variable (x-axis) and dependent variable (y-axis) before reading any question.
  • Check units and scale on every axis — a jump from 10-20-40 is not evenly spaced.
  • For multi-line graphs, note which line represents which condition using the legend before comparing them.
  • Interpolation (estimating a value between two plotted points) is common; extrapolation (beyond the data) is riskier and less often correct.
  • When a question references 'Table 1' or 'Figure 2,' go straight to that figure — don't reread the whole passage.
  • Trends (increasing, decreasing, constant, or no clear pattern) are the most frequently tested relationship type.

Experimental Design Concepts

Research Summaries test understanding of how experiments are structured, not memorized science facts.
  • The independent variable is what the experimenter changes; the dependent variable is what is measured.
  • A control group/trial is used as a baseline for comparison and typically has no treatment applied.
  • Variables held constant across trials are 'controlled variables,' meant to isolate the effect of the one variable being tested.
  • Comparing two experiments usually means identifying exactly what changed between them and what stayed the same.
  • 'Why did the researchers include a control?' answers should reference isolating the effect of the independent variable.
  • Repeating trials increases reliability of results, not necessarily accuracy of a single measurement.

Conflicting Viewpoints Strategy

This passage type tests reading comprehension applied to scientific arguments rather than data analysis.
  • Make a quick note of each scientist's core claim and the evidence/mechanism they cite for it.
  • Identify what all viewpoints agree on versus where they diverge — agreement points are common question targets.
  • 'Which scientist would most likely agree with the following statement' questions require matching the statement's logic to one viewpoint's reasoning.
  • New data presented in a question can support one viewpoint and contradict another — check both.
  • Avoid using outside scientific knowledge to judge which viewpoint is 'more correct' — the ACT only tests reading comprehension here.
  • Track terminology differences between viewpoints, since one scientist's specific term may not apply to another's model.

Scientific Method and Units Basics

A small amount of outside science knowledge — mostly about method and measurement — does appear on the ACT.
  • A hypothesis is a testable, falsifiable prediction, not simply a guess.
  • Correlation between two variables does not by itself establish causation.
  • Common metric units (grams, liters, meters, °C) may appear; know basic prefixes like kilo- (1000x) and milli- (1/1000).
  • A directly proportional relationship means both variables increase together; inversely proportional means one increases as the other decreases.
  • Significant figures/precision in a table can hint at measurement reliability but rarely require calculation.
  • The scientific method process: observation, hypothesis, experiment, analysis, conclusion.
Trying to apply memorized science class facts instead of reading the given data or viewpoint carefully.
Confusing which axis is the independent variable versus the dependent variable on a graph.
Assuming a trend continues beyond the plotted data range (extrapolating) when the question only supports interpolation.
Mixing up two scientists' viewpoints in Conflicting Viewpoints passages because their terminology overlaps.

Essay Prompt Structure

The ACT Writing prompt always presents an issue and three different perspectives on it, asking you to develop your own position.
  • You get 40 minutes to read the prompt, plan, write, and proofread a single essay.
  • The three given perspectives typically represent different value trade-offs — read all three before choosing your position.
  • You may agree fully with one perspective, partially agree, or synthesize elements of two — full agreement isn't required for a high score.
  • Your essay must explicitly discuss the relationship between your own perspective and at least one of the given perspectives.
  • Prompts are usually about broad social or ethical issues (technology, education, community) accessible without specialized knowledge.
  • Spend the first 5 minutes planning before writing — a clear plan matters more than a fast start.

The Four Scoring Domains

ACT Writing is scored by two graders on four domains, each on a 1-6 scale, then combined into a final 2-12 score.
  • Ideas and Analysis: the depth and clarity of your argument and your engagement with multiple perspectives.
  • Development and Support: how well you use specific reasoning, examples, and evidence to back up claims.
  • Organization: a clear structure with logical progression, effective transitions, and a strong intro/conclusion.
  • Language Use: sentence variety, word choice, and control of grammar/mechanics appropriate for a timed essay.
  • All four domains are weighted equally, so a paper with a brilliant idea but poor organization won't earn a top score.
  • The essay score does not count toward your Composite score — it is reported separately.

Building a Strong Thesis and Structure

A clear five-paragraph structure with an explicit thesis gives graders an easy way to award points.
  • State your own perspective clearly in the introduction, including how it relates to the given perspectives.
  • Use one body paragraph per major point of support, each starting with a clear topic sentence.
  • Dedicate at least one paragraph to directly analyzing a perspective you disagree with or complicate.
  • Use concrete examples (historical, personal, or hypothetical) rather than vague generalizations.
  • End with a conclusion that reinforces your thesis and briefly acknowledges the broader significance of the issue.
  • Avoid restating the prompt word-for-word in your introduction; paraphrase it briefly instead.

Analyzing Multiple Perspectives

The highest-scoring essays don't just state an opinion — they actively compare and evaluate the given perspectives.
  • Summarize each of the three perspectives accurately before critiquing or building on any of them.
  • Explain the underlying value or assumption behind each perspective (e.g., prioritizing efficiency vs. fairness).
  • Show how your own view addresses a limitation or blind spot in at least one given perspective.
  • Avoid a simple 'perspective one is right, the others are wrong' approach — nuanced engagement scores higher.
  • Use transition phrases like 'while this view assumes X, it overlooks Y' to signal analytical depth.
  • Address counterarguments to your own position, then explain why your reasoning still holds.

Time Management for the Essay

With only 40 minutes total, allocating time deliberately across planning, writing, and revising prevents an unfinished essay.
  • Spend about 5 minutes reading the prompt and the three perspectives carefully.
  • Spend about 5 minutes outlining your thesis and body paragraph structure.
  • Spend about 25 minutes writing the full essay, aiming for roughly 4-5 paragraphs.
  • Reserve the last 5 minutes for proofreading grammar, spelling, and clarity — not for major rewrites.
  • Write legibly; graders can only score what they can read within their limited grading time.
  • If running short on time, prioritize finishing your conclusion over adding another body paragraph.
Simply restating all three perspectives without ever developing your own distinct argument.
Ignoring the given perspectives entirely and writing a generic essay on the topic.
Ending abruptly without a conclusion because too much time was spent on body paragraphs.
Using only vague, general claims with no specific examples or reasoning to back them up.

Section-by-Section Time Budgets

Each ACT section has a fixed time limit and question count, so knowing your per-question budget prevents running out of time.
  • English: 75 questions / 45 minutes ≈ 36 seconds per question.
  • Math: 60 questions / 60 minutes = 1 minute per question, front-loaded easier at the start.
  • Reading: 40 questions / 35 minutes ≈ 8-9 minutes per passage (including reading time).
  • Science: 40 questions / 35 minutes ≈ 5 minutes per passage.
  • Writing (optional): 1 essay / 40 minutes, split roughly 5/5/25/5 across reading, planning, writing, and proofreading.
  • Build in a 2-3 minute buffer per section for review of flagged/skipped questions.

Pacing Checkpoints

Using checkpoints during a section prevents discovering you're behind schedule only when time is called.
  • Check the clock at the midpoint of each section — you should be roughly at the halfway question count.
  • In Math, expect to be through question 30 by the 30-minute mark; adjust pace if significantly behind.
  • In Reading/Science, use the passage transition as a natural checkpoint rather than checking the clock mid-passage.
  • If behind pace, switch to answering only questions you can solve in under 30 seconds, and guess/flag the rest.
  • If ahead of pace, use the extra time to double check flagged questions rather than slowing down overall.
  • Practice with a visible timer during prep so checkpoint pacing becomes automatic on test day.

The Two-Pass Strategy

Answering every 'easy for you' question first, then returning for harder ones, maximizes points per minute.
  • On your first pass through a section, answer every question you can solve quickly and skip (but mark) the rest.
  • Never leave a bubble blank on your first pass — fill in a guess, then revisit if time allows.
  • On the second pass, spend remaining time only on marked/flagged questions, starting with ones that seem most solvable.
  • This strategy protects against running out of time before reaching easier questions later in a section.
  • Two-pass works especially well on Math, where difficulty roughly increases with question number.
  • For Reading/Science, apply two-pass within each passage rather than across the whole section.

Guessing Strategy and No Penalty for Wrong Answers

The ACT's scoring rewards guessing over leaving blanks, which should shape late-section decisions.
  • There is no penalty for incorrect answers, so every question should have a bubble filled in before time is called.
  • If you must guess blindly, pick one 'letter of the day' (e.g., always C) and use it consistently for speed.
  • Eliminating even one implausible choice before guessing meaningfully raises your odds versus a blind guess.
  • Reserve the last minute of any section to bubble in guesses for all remaining unanswered questions.
  • Never spend more than 60-90 seconds total deciding whether to guess on a single stuck question.
  • Guessing strategically (eliminating options) beats guessing randomly, but both beat leaving a blank.

Full-Test Time Management

The whole ACT (excluding Writing) runs about 2 hours and 55 minutes, and stamina management matters as much as per-section pacing.
  • Standard test order is English, Math, (short break), Reading, Science, (Writing if taken).
  • A 10-15 minute break typically occurs after Math — use it to hydrate, stretch, and mentally reset, not to review answers.
  • Fatigue tends to hit hardest in Science (the last multiple-choice section), so practice full-length tests to build stamina.
  • Avoid perfectionism on any single section; a poor Math section shouldn't be allowed to bleed into your Reading mindset.
  • Simulate full-length, timed practice tests at least 2-3 times before test day to calibrate real pacing.
  • Track your actual per-section timing in practice to identify which section needs the most pacing work.
Spending 3+ minutes on a single hard question instead of marking it and moving on.
Leaving questions blank because you didn't reach them, instead of guessing before time is called.
Ignoring pacing checkpoints and only realizing you're behind schedule near the end of a section.
Using break time to obsess over a previous section instead of resting for the next one.

English: Grammar vs. Rhetorical Skills Questions

English questions fall into two broad families that require different approaches: fixing errors versus improving effectiveness.
  • Grammar/usage questions (punctuation, agreement, verb tense) have one objectively correct answer based on rules.
  • Rhetorical skills questions (organization, style, strategy) ask which choice best fits the writer's purpose or the paragraph's logic.
  • Underlined-portion questions test grammar most often; 'whole passage' questions (often at the end) test rhetorical skills.
  • Tense consistency questions require checking the tense used elsewhere in the same paragraph, not just the sentence.
  • Questions asking to 'add a sentence that provides...' require matching content to a specific stated purpose.
  • 'Which choice is NOT acceptable' questions flip the usual approach — find the option that breaks a rule.

Math: Question Formats and Traps

ACT Math questions repeat a handful of formats; recognizing the format quickly speeds up solving.
  • 'Solve for x' questions want a numeric or algebraic answer — check whether the choices are numbers or expressions.
  • 'Which of the following must be true' questions require checking ALL cases, not just one example that seems to work.
  • 'Which of the following could be true' questions only need ONE valid example to justify an answer.
  • Word problems often bury a trap by asking for a value related to, but not identical to, what you first solve for (e.g., solving for x when the question asks for x+3).
  • Diagram-based geometry problems may not be drawn to scale — never estimate an answer purely from the picture.
  • 'Approximately' in a question signals it's fine (and often faster) to estimate rather than calculate exactly.

Reading: Detail, Inference, and Big-Picture Questions

Reading questions split into three main categories, each requiring a different search strategy in the text.
  • Detail questions ask 'what does the passage state' — the answer is a near-paraphrase of an explicit sentence.
  • Inference questions ask 'what can reasonably be concluded' — the answer requires one small logical step beyond the text.
  • Big-picture questions ask about the main idea, purpose, or tone of an entire passage or paragraph.
  • Vocabulary-in-context questions test the meaning of a word AS USED in that specific sentence, not its most common definition.
  • Comparison questions in paired passages ask how the two authors' views relate — look for explicit points of agreement/disagreement.
  • Function questions ask why the author included a specific detail, example, or paragraph.

Science: Trend, Comparison, and Prediction Questions

Science questions almost always ask you to read a trend, compare data points, or predict an unlisted value.
  • Trend questions ask how one variable changes as another changes — read the direction directly off the graph/table.
  • Comparison questions ask you to evaluate two or more trials, figures, or scientists' claims against each other.
  • Prediction questions ask for a value not directly shown — check whether it falls within the data range (interpolation, safer) or beyond it (extrapolation, riskier).
  • 'Which figure supports the statement' questions require matching a claim to specific numbers, not general impressions.
  • Questions with 'if only Table 1 were used' logic test whether you understand what each specific data set does and doesn't show.
  • Questions about experimental flaws or improvements test understanding of controls and variables, not outside science facts.

Recognizing Question Stems Fast

Learning to recognize a question type from its first few words saves seconds you can reinvest across the section.
  • 'According to the passage/table' signals a direct-lookup question with no inference required.
  • 'It can be inferred/reasonably assumed' signals you need a small logical extension of stated facts.
  • 'The author's primary purpose' or 'the main idea' signals a big-picture question — don't over-focus on one detail.
  • 'Which choice best maintains the sentence pattern' or 'is most consistent with the writer's tone' signals a style-matching question.
  • 'If the experiment were repeated with...' signals a hypothetical scenario question requiring you to apply, not just read, the data.
  • Questions naming a specific paragraph, line, figure, or table number should send you straight there, not to the whole passage.
Treating an inference question like a detail question and demanding the exact wording appear in the text.
Assuming a 'must be true' answer is correct after checking only one example instead of all possible cases.
Extrapolating far beyond a graph's data range and treating the result as equally reliable as interpolation.
Ignoring the specific figure/table/line reference in a question and rereading the entire passage instead.

Building a Study Schedule

A structured multi-week plan targeting weak areas outperforms unfocused, last-minute review.
  • Take one full-length diagnostic test first to identify your baseline score and weakest section.
  • Allocate more weekly study time to your lowest-scoring section, but don't neglect strong sections entirely.
  • Plan for at least one full-length, timed practice test every 1-2 weeks to track progress under real conditions.
  • Leave the final 2-3 days before the test for light review only — avoid new content or heavy cramming.
  • Space practice sessions across multiple days rather than cramming, since spaced repetition improves retention.
  • Track score trends across practice tests, not just the raw score of the most recent one.

Reviewing Missed Questions Effectively

How you review practice questions matters more for improvement than how many you complete.
  • For every missed question, identify WHY you missed it: content gap, careless error, timing pressure, or misread question.
  • Keep an error log categorizing mistakes by type (e.g., comma rules, inference questions) to spot patterns.
  • Redo missed math and science questions without looking at the solution first, to test if it was a fluke or a true gap.
  • For English/Reading, go back to the passage and locate the exact textual evidence for the correct answer.
  • Review correct-but-slow answers too — a right answer that took 3 minutes reveals a pacing weakness.
  • Revisit your error log weekly to confirm previously weak categories are improving.

Simulating Real Test Conditions

Practicing under conditions that mirror test day reduces surprises and anxiety on the actual exam.
  • Take full-length practice tests in one sitting with only the official short break, not spread across days.
  • Use an actual answer sheet and bubble in answers (or a timed digital interface) rather than circling in the book.
  • Practice with the same calculator you'll bring on test day so you're fluent with its functions.
  • Sit in a quiet space free of phone notifications to build focus stamina for the full ~3 hours.
  • Time each section strictly with a stopwatch or timer, stopping exactly when time is called, even mid-question.
  • Simulate the optional Writing test too if you plan to take it, since it adds 40 minutes of additional stamina demand.

Score Reports and Target Setting

Understanding how ACT scores are calculated helps set realistic, motivating goals.
  • Each of the four main sections is scored 1-36; the Composite score is the rounded average of all four.
  • A raw score (number correct) converts to a scaled score via a table that varies slightly by test form.
  • Colleges often superscore, averaging your best section scores across multiple test dates — check each target school's policy.
  • Set a target Composite score based on the middle 50% range of admitted students at your target colleges.
  • Focus on your single lowest-scoring section for the biggest potential Composite score gain.
  • A 1-2 point Composite gain often requires answering just a few more questions correctly across sections.

Test-Day Logistics and Mindset

Physical preparation and a calm mindset are as much a part of an ACT strategy as content mastery.
  • Confirm your test center, start time, and required ID the night before, and lay out materials in advance.
  • Bring an approved calculator, several No. 2 pencils, a photo ID, and your admission ticket.
  • Eat a balanced meal beforehand and bring an approved snack for the break to maintain energy.
  • Arrive early to reduce pre-test stress; rushing in late increases anxiety and error rates.
  • Use brief breathing resets between sections rather than dwelling on a section you felt went poorly.
  • Remember one weak section doesn't determine your Composite — stay focused on the section in front of you.
Taking many practice tests without ever reviewing why questions were missed.
Cramming new content in the final 1-2 days instead of resting and doing light review.
Ignoring pacing during practice tests by pausing the clock, which hides real timing weaknesses.
Focusing study time evenly across all sections instead of prioritizing the lowest-scoring one for the biggest gain.

Unit 1: English Section Tactics

Comma Splice
Two independent clauses incorrectly joined by only a comma; fix with a period, semicolon, or comma+conjunction.
Restrictive Clause
A clause essential to the sentence's meaning (e.g., 'that' clauses); takes no surrounding commas.
Nonrestrictive Clause
A clause with extra, non-essential info (often starting with 'which' or a name+appositive); set off by commas on both sides.
Colon Rule
Must follow a complete independent clause; introduces a list, explanation, or quotation—never follows a verb or preposition directly.
Semicolon Rule
Joins two independent clauses without a conjunction, or separates items in a complex list.
Dangling Modifier
An introductory phrase whose implied subject doesn't match the sentence's actual subject, creating illogical meaning.
Parallel Structure
Items in a list or comparison must share the same grammatical form (all gerunds, all infinitives, etc.).
Redundancy
Repeating the same idea with different words (e.g., 'return back'); the ACT rewards the more concise, non-repetitive choice.
Writer's Goal Question
Asks whether a proposed addition/edit accomplishes a specific stated purpose—judge strictly against that stated goal, not general quality.
NO CHANGE
The answer choice indicating the original underlined text is already correct; correct roughly 25% of the time.

Unit 2: Math Section Tactics

Backsolving
Plugging answer choices into the original equation (starting with a middle value) instead of solving algebraically from scratch.
Plugging In Numbers
Substituting a smart specific number for a variable in 'for all x' problems to quickly test which answer choice matches.
Pythagorean Theorem
a² + b² = c², where c is the hypotenuse of a right triangle; used constantly in ACT geometry.
Slope Formula
(y2 - y1)/(x2 - x1); measures the steepness/direction of a line between two points.
Difference of Squares
a² - b² factors as (a - b)(a + b); a common ACT factoring pattern.
Similar Triangles Area Scaling
If linear dimensions scale by factor k, area scales by k²and volume scales by k³.
Inverse Variation
A relationship y = k/x, where y decreases as x increases (contrast with direct variation y = kx).
SOH-CAH-TOA
Mnemonic for right-triangle trig: sin=opposite/hypotenuse, cos=adjacent/hypotenuse, tan=opposite/adjacent.
Sum of Interior Angles
For a polygon with n sides, the sum of interior angles is (n-2) × 180°.
Flipping Inequality Signs
Multiplying or dividing both sides of an inequality by a negative number reverses the inequality's direction.

Unit 3: Reading Speed Strategies

Detail Question
Asks for a fact directly and explicitly stated in the passage—no inference required.
Inference Question
Requires a small, text-supported logical step beyond what is explicitly stated.
Paired Passages
One ACT Reading slot containing two shorter, related passages with added comparison questions.
Vocabulary-in-Context
A question testing a word's meaning as used in the passage, often a secondary/less common definition.
Function Question
Asks why the author included a specific sentence or paragraph—its rhetorical purpose in the passage.
EXCEPT/LEAST Question
Asks you to find the one choice NOT supported by the text, while the others are supported.
Line Reference Strategy
Read a sentence or two before and after the cited line, not just the exact line, for full context.
No Guessing Penalty
The ACT does not deduct points for wrong answers, so every question should be answered.
Extreme Language Trap
Answer choices with words like 'always' or 'never' are usually wrong unless explicitly proven by the text.
Text-Based Evidence
The defining trait of a correct ACT Reading answer: it can be traced back to specific passage wording, not just general plausibility.

Unit 4: Science Reasoning

Data Representation Passage
An ACT Science passage centered on interpreting given graphs, tables, or charts.
Research Summaries Passage
An ACT Science passage describing one or more experiments (methods and results) for analysis.
Conflicting Viewpoints Passage
An ACT Science passage presenting two or more disagreeing hypotheses, evaluated mainly through text.
Independent Variable
The variable a scientist deliberately manipulates in an experiment; typically plotted on the x-axis.
Dependent Variable
The variable measured as an outcome/result of the experiment; typically plotted on the y-axis.
Interpolation
Estimating a value that falls between two known, plotted data points.
Extrapolation
Estimating a value beyond the range of the given data—riskier since the trend may not continue.
Control Group
A baseline group in an experiment that does not receive the tested variable, used for comparison.
Confounding Variable
An uncontrolled variable that could affect the outcome, making it hard to isolate the true cause.
Positive vs. Negative Correlation
Positive: both variables increase together. Negative: one increases as the other decreases.

Unit 5: Writing (Optional) Overview

ACT Writing Test
An optional 40-minute essay section not included in the Composite score, but sometimes requested by colleges.
Essay Score Range
2-12, formed from four domain scores, each an average of two graders' 1-6 ratings.
Four Writing Domains
Ideas & Analysis, Development & Support, Organization, and Language Use.
Given Perspectives
Three differing viewpoints on an issue provided in the prompt; strong essays engage critically with at least one.
Ideas & Analysis
The domain assessing depth and critical thinking in how you engage with the issue and perspectives.
Development & Support
The domain assessing how well claims are explained and backed with reasoning or examples.
Organization (Essay)
The domain assessing logical structure, paragraphing, and transitions in the essay.
Language Use
The domain assessing grammar, word choice, sentence variety, and clarity of expression.
Thesis Statement
A clear statement of your position on the issue, ideally established early to guide the essay's structure.
Counterargument Engagement
Acknowledging and responding to an opposing view within the body paragraphs, which strengthens analytical depth.

Unit 6: Timing Frameworks

English Section Timing
The ACT English section gives 45 minutes for 75 questions, about 36 seconds per question, spread across five passages.
Math Section Timing
The ACT Math section gives 60 minutes for 60 questions, roughly one minute per question, with difficulty generally increasing.
Reading Section Timing
The ACT Reading section gives 35 minutes for 40 questions across four passages, about 8-9 minutes per passage including reading and answering.
Science Section Timing
The ACT Science section gives 35 minutes for 40 questions across six or seven passages, roughly 5 minutes per passage.
Writing Section Timing
The optional ACT Writing test gives 40 minutes to plan, write, and revise a single essay.
Two-Pass Strategy
On timed sections, answer every question you find easy on a first pass, then return to skipped or difficult questions on a second pass.
No Guessing Penalty
The ACT does not subtract points for wrong answers, so never leave a bubble blank — always fill in a guess before time runs out.
Pace Checkpoints
Check the clock at fixed checkpoints (like the halfway point) during each section to confirm you're on pace to finish.
Bubble-Sheet Buffer
Reserve the last 1-2 minutes of a section to transfer and verify answers on the bubble sheet, avoiding rushed misbubbling at the end.
Passage-Order Flexibility
On Reading and Science, you may answer passages in any order, so tackle the easiest passage first to bank points before harder ones.

Unit 7: Question Type Patterns

NO CHANGE Pattern
On ACT English, recognize when the underlined portion is already correct and concise — NO CHANGE is correct roughly a quarter of the time.
Concision Pattern
When English answer choices differ mainly in length, the shortest option that remains grammatically correct and complete is usually right.
EXCEPT/LEAST Question Pattern
For 'EXCEPT' or 'LEAST' questions, every wrong answer choice actually fits the criteria — find the one choice that does not.
Vocabulary-in-Context Pattern
For vocabulary-in-context questions, plug each answer choice back into the sentence and judge by the passage's context, not the word's most common dictionary meaning.
Data-Representation Pattern
Science 'Data Representation' questions can usually be answered by directly reading a graph or table, without outside science knowledge.
Cannot-Be-Determined Trap
Only choose 'cannot be determined' on Math questions when the given information is genuinely insufficient — it's often a trap for questions that are solvable.
Must-Be-True Pattern
'Must be true' Reading questions require a statement to hold under every scenario the passage supports; one exception is enough to eliminate it.
Paired-Passage Comparison Pattern
Paired-passage questions typically ask how the two authors' viewpoints agree or disagree — locate each author's stance before comparing.
Writer's Goal Pattern
'Writer's goal' questions are graded strictly against the stated purpose in the question, not general writing quality.
Extreme-Qualifier Trap
When two answer choices differ by one qualifying word (like 'always' vs. 'often'), extreme qualifiers are frequently wrong unless directly supported by the text.

Unit 8: Full Practice Workflow

Full-Length Timed Practice
Take complete practice tests under real timing and conditions to build stamina and get an accurate score estimate.
Error Log
Track every missed question by section and category (e.g., comma usage, inference) to reveal recurring weak spots to target.
Prompt Review Within 24 Hours
Review missed questions within a day of taking a practice test, while your reasoning process is still fresh enough to diagnose mistakes.
Simulate Test-Day Conditions
Practice with the same wake time, breaks, and no-phone rule as real test day so the actual exam feels familiar.
Standard Section Order
The ACT is always given in the order English, Math, Reading, Science, then the optional Writing test — practice in that same order.
Target-Score Planning
Calculate the section score improvements needed to reach your composite goal, then prioritize practice on the sections with the most room to grow.
Spaced Practice Tests
Schedule full practice tests roughly every 1-2 weeks rather than back-to-back, leaving time to review and apply lessons before the next one.
Post-Test Pacing Analysis
After each practice test, identify which section you ran out of time on and adjust your pacing plan for that section specifically.
Use Official Retired Tests
Practice with official, retired ACT tests whenever possible — they most accurately reflect real question style and difficulty.
Final-Week Taper
In the week before the real test, reduce full practice tests and shift to light review and confidence-building instead of heavy new drilling.

Unit 1: English Section Tactics

Comma Rules That Get Tested
Most ACT English comma questions test three patterns: unnecessary commas, missing commas around nonessential info, and comma splices.
Semicolons, Colons, and Dashes
These three punctuation marks are ACT favorites because students often use them interchangeably when they shouldn't be.
Redundancy and Wordiness (Concision)
When answer choices differ mainly in length, the ACT usually rewards the shortest option that preserves meaning and grammar.
Subject-Verb and Pronoun Agreement
Agreement errors are hidden by long prepositional phrases or lists inserted between the subject and the verb.
Rhetorical Skills: Transitions, Order, and Purpose
About a quarter of English questions ask about the passage as a whole rather than grammar — these test logic and organization.
Apostrophes and Word Choice Pairs
The ACT frequently tests commonly confused words and possessive forms in the same passage.
Key fact
The English test has 75 questions in 45 minutes across 5 passages — about 9 minutes per passage.
Key fact
Roughly 40% of questions test grammar/usage (punctuation, agreement) and 60% test rhetorical skills (style, organization, strategy).
Key fact
When choices vary only in punctuation, identify whether the surrounding clauses are independent or dependent first.
Key fact
'NO CHANGE' is correct about 25% of the time — don't avoid it just because it feels too easy.

Unit 2: Math Section Tactics

Backsolving and Plugging In Answers
When a question asks for a specific numeric value and gives answer choices, working backward from the choices is often faster than solving algebraically.
Plugging In Numbers for Variables
For problems with variables in both the question and the answer choices, substituting simple numbers avoids abstract algebra errors.
Key Geometry Formulas
The ACT math section leans heavily on a small set of geometry formulas that appear across many question types.
Algebra and Function Manipulation
Function notation and systems of equations questions reward recognizing structure quickly rather than brute-force solving.
Calculator Strategy and Time Management
A calculator can speed up arithmetic but can also cost time if used on problems better solved with reasoning.
Statistics, Probability, and Data Interpretation
The ACT tests basic statistics and probability concepts, often embedded in tables, graphs, or word problems.
Key fact
The Math test has 60 questions in 60 minutes — pace roughly one question per minute, but the first 20 are usually easier and faster.
Key fact
Calculators are allowed for the entire math section (per current ACT policy), but strategic use matters more than calculator speed.
Key fact
Roughly 60% of questions cover algebra and functions, and roughly 40% cover geometry, statistics, and probability combined.
Key fact
Skipping a hard question and returning later beats spending 5 minutes stuck on one problem.

Unit 3: Reading Speed Strategies

Passage Mapping Instead of Full Reading
With only about 8-9 minutes per passage including questions, skimming for structure beats reading every word closely.
Order of Passages and Question Triage
You control the order you tackle the four passages, and picking wisely protects your overall score.
Using Line References and Context
Most reading questions point you to a specific location — using that window efficiently is the core reading skill tested.
Author's Purpose and Tone
Many big-picture questions ask why the author included something or how they feel about the topic.
Eliminating Wrong Answer Patterns
ACT Reading wrong answers follow predictable patterns that can be spotted and eliminated quickly.
Key fact
The Reading test has 40 questions across 4 passages in 35 minutes — about 8-9 minutes per passage including questions.
Key fact
There is no penalty for wrong answers, so every question should be answered, even if guessed.
Key fact
Paired passages (two shorter related passages) appear in one of the four slots and include comparison questions.
Key fact
Correct answers are almost always directly supported by the text, not by outside knowledge or opinion.

Unit 4: Science Reasoning

The Three Passage Types
ACT Science has three recurring passage formats, and knowing which one you're facing tells you how to attack it.
Reading Graphs and Tables Efficiently
Most Science questions can be answered without reading the passage text at all — just the figures.
Experimental Design Concepts
Research Summaries test understanding of how experiments are structured, not memorized science facts.
Conflicting Viewpoints Strategy
This passage type tests reading comprehension applied to scientific arguments rather than data analysis.
Scientific Method and Units Basics
A small amount of outside science knowledge — mostly about method and measurement — does appear on the ACT.
Key fact
The Science test has 40 questions across 6-7 passages in 35 minutes — roughly 5 minutes per passage.
Key fact
About 90% of questions can be answered directly from the given data without outside science knowledge.
Key fact
Data Representation and Research Summaries passages together make up most of the section; Conflicting Viewpoints is usually just 1 passage.
Key fact
Answering figure-based questions before reading passage text often saves significant time.

Unit 5: Writing (Optional) Overview

Essay Prompt Structure
The ACT Writing prompt always presents an issue and three different perspectives on it, asking you to develop your own position.
The Four Scoring Domains
ACT Writing is scored by two graders on four domains, each on a 1-6 scale, then combined into a final 2-12 score.
Building a Strong Thesis and Structure
A clear five-paragraph structure with an explicit thesis gives graders an easy way to award points.
Analyzing Multiple Perspectives
The highest-scoring essays don't just state an opinion — they actively compare and evaluate the given perspectives.
Time Management for the Essay
With only 40 minutes total, allocating time deliberately across planning, writing, and revising prevents an unfinished essay.
Key fact
The Writing test is optional and not included in your Composite score, but many colleges request it.
Key fact
The essay is scored on a 2-12 scale, averaging four domain scores from two graders each scored 1-6.
Key fact
You must engage with at least one of the three given perspectives, not just state your own opinion in isolation.
Key fact
Length alone doesn't earn points — a well-organized, well-supported shorter essay beats a rambling long one.

Unit 6: Timing Frameworks

Section-by-Section Time Budgets
Each ACT section has a fixed time limit and question count, so knowing your per-question budget prevents running out of time.
Pacing Checkpoints
Using checkpoints during a section prevents discovering you're behind schedule only when time is called.
The Two-Pass Strategy
Answering every 'easy for you' question first, then returning for harder ones, maximizes points per minute.
Guessing Strategy and No Penalty for Wrong Answers
The ACT's scoring rewards guessing over leaving blanks, which should shape late-section decisions.
Full-Test Time Management
The whole ACT (excluding Writing) runs about 2 hours and 55 minutes, and stamina management matters as much as per-section pacing.
Key fact
Total ACT time (without Writing) is about 2 hours 55 minutes across English, Math, Reading, and Science.
Key fact
Math is the only section giving a full 1 minute per question on average; others require faster pacing.
Key fact
There is no penalty for wrong answers on the ACT, so guessing is always better than leaving a blank.
Key fact
A short break follows Math, before Reading and Science — plan hydration and a stretch around it.

Unit 7: Question Type Patterns

English: Grammar vs. Rhetorical Skills Questions
English questions fall into two broad families that require different approaches: fixing errors versus improving effectiveness.
Math: Question Formats and Traps
ACT Math questions repeat a handful of formats; recognizing the format quickly speeds up solving.
Reading: Detail, Inference, and Big-Picture Questions
Reading questions split into three main categories, each requiring a different search strategy in the text.
Science: Trend, Comparison, and Prediction Questions
Science questions almost always ask you to read a trend, compare data points, or predict an unlisted value.
Recognizing Question Stems Fast
Learning to recognize a question type from its first few words saves seconds you can reinvest across the section.
Key fact
Each of the four multiple-choice sections has 4 answer choices (A-D or F-J), unlike the SAT's 4-option format for all questions too.
Key fact
Recognizing whether a question is asking for an explicit detail versus an inference changes how much text-searching you need to do.
Key fact
'Must be true' requires checking every case; 'could be true' requires only a single valid example.
Key fact
Odd-numbered English answer choices are labeled A-D and even-numbered ones F-J to make bubble sheets easier to read.

Unit 8: Full Practice Workflow

Building a Study Schedule
A structured multi-week plan targeting weak areas outperforms unfocused, last-minute review.
Reviewing Missed Questions Effectively
How you review practice questions matters more for improvement than how many you complete.
Simulating Real Test Conditions
Practicing under conditions that mirror test day reduces surprises and anxiety on the actual exam.
Score Reports and Target Setting
Understanding how ACT scores are calculated helps set realistic, motivating goals.
Test-Day Logistics and Mindset
Physical preparation and a calm mindset are as much a part of an ACT strategy as content mastery.
Key fact
Consistent, spaced full-length practice tests are the single best predictor of ACT score improvement.
Key fact
An error log that categorizes WHY you missed each question turns practice into targeted improvement.
Key fact
The Composite score is the rounded average of the four 1-36 section scores (English, Math, Reading, Science).
Key fact
Many colleges superscore the ACT, so strategic retesting focused on your weakest section can raise your Composite.
Common mistakes for each unit — read the mistake, then make sure you know why it's wrong.

Unit 1: English Section Tactics

Watch out
Choosing the most 'formal-sounding' answer, not the grammatically correct or most concise one.
Watch out
Adding a comma wherever you would naturally pause when reading aloud, rather than following a comma rule.
Watch out
Answering rhetorical 'writer's goal' questions based on general quality of writing, not the stated goal.
Watch out
Fixing only the underlined error and ignoring how the sentence fits the surrounding paragraph.

Unit 2: Math Section Tactics

Watch out
Solving with full algebra when plugging in numbers or backsolving would be faster and less error-prone.
Watch out
Choosing 0 or 1 when plugging in numbers, which can make several answer choices appear correct.
Watch out
Forgetting to flip an inequality sign when multiplying or dividing by a negative number.
Watch out
Misreading a graph's scale or units, leading to an answer that's off by a factor of 10 or more.

Unit 3: Reading Speed Strategies

Watch out
Rereading the entire passage from scratch to answer each question instead of using line references.
Watch out
Picking an answer because it sounds sophisticated rather than because the text supports it.
Watch out
Confusing a detail question (needs proof from the text) with an inference question (needs a small logical step).
Watch out
Getting stuck on a hard vocabulary-in-context question instead of substituting your own word first.

Unit 4: Science Reasoning

Watch out
Trying to apply memorized science class facts instead of reading the given data or viewpoint carefully.
Watch out
Confusing which axis is the independent variable versus the dependent variable on a graph.
Watch out
Assuming a trend continues beyond the plotted data range (extrapolating) when the question only supports interpolation.
Watch out
Mixing up two scientists' viewpoints in Conflicting Viewpoints passages because their terminology overlaps.

Unit 5: Writing (Optional) Overview

Watch out
Simply restating all three perspectives without ever developing your own distinct argument.
Watch out
Ignoring the given perspectives entirely and writing a generic essay on the topic.
Watch out
Ending abruptly without a conclusion because too much time was spent on body paragraphs.
Watch out
Using only vague, general claims with no specific examples or reasoning to back them up.

Unit 6: Timing Frameworks

Watch out
Spending 3+ minutes on a single hard question instead of marking it and moving on.
Watch out
Leaving questions blank because you didn't reach them, instead of guessing before time is called.
Watch out
Ignoring pacing checkpoints and only realizing you're behind schedule near the end of a section.
Watch out
Using break time to obsess over a previous section instead of resting for the next one.

Unit 7: Question Type Patterns

Watch out
Treating an inference question like a detail question and demanding the exact wording appear in the text.
Watch out
Assuming a 'must be true' answer is correct after checking only one example instead of all possible cases.
Watch out
Extrapolating far beyond a graph's data range and treating the result as equally reliable as interpolation.
Watch out
Ignoring the specific figure/table/line reference in a question and rereading the entire passage instead.

Unit 8: Full Practice Workflow

Watch out
Taking many practice tests without ever reviewing why questions were missed.
Watch out
Cramming new content in the final 1-2 days instead of resting and doing light review.
Watch out
Ignoring pacing during practice tests by pausing the clock, which hides real timing weaknesses.
Watch out
Focusing study time evenly across all sections instead of prioritizing the lowest-scoring one for the biggest gain.
