We have a lot of great stuff on our blog here about the ACT’s question types, but not all in one place! So here’s your complete guide to all of the question types that appear on the ACT exam, with links to sample questions (with video and text explanations for the answers) and more help!
Content-wise, there are two basic question types on the ACT English test: first, those that test your knowledge of proper English grammar and usage, and second, those that test your understanding of good writing. The former are categorized as Usage/Mechanics questions and the latter are called Rhetorical Skills questions.
- Punctuation: these questions are about identifying and correcting misplaced, missing, or unnecessary commas, apostrophes, colons, semicolons, dashes, periods, question marks, and exclamation points.
- Grammar and usage: these questions are mostly about subject/verb agreement, pronoun agreement, cases and forms, adjectives, adverbs, verb forms, comparative and superlative modifiers, and idioms.
- Sentence structure: these questions are mostly about the relationships between independent and dependent clauses, run-on sentences, comma splices, sentence fragments, misplaced modifiers, shifts in verb tense or voice, and shifts in pronoun person or number
- Strategy: these questions are about the choices and strategies a writer makes in putting together an essay. They are often about the appropriateness of a sentence or the overall essay in terms of the essay’s purpose, focus and audience, or about the effect of adding, deleting, or revising phrases and sentences in the essay.
- Organization: these questions typically have to do with the order and coherence of sentences or paragraphs within an essay, or where a phrase should go within a sentence.
- Style: these questions are about choosing the most effective choice in terms of style, tone, clarity and conciseness. Pro tip: always eliminate wordiness and redundancy on the ACT.
Structurally speaking, all of the ACT Math questions are basically the same. They are all multiple choice, but what most students want to know is what topics are tested on the Math test, so here we go.
- Pre Algebra: questions are mostly about basic operations, decimals, fractions, square roots, factors, ratios, percents, one variable equations, simple counting techniques and probability, and understanding basic descriptive statistics.
- Elementary Algebra: questions are mostly about exponents and square roots, evaluating algebraic expressions through substitution, using variables to express relationships and factoring quadratic equations.
- Intermediate Algebra: questions are mainly about understanding the quadratic formula, rational and radical expressions, absolute value equations and inequalities, sequences, systems of equations, quadratic inequalities, roots of polynomials, complex numbers, and matrices.
- Coordinate Geometry: questions are mostly about graphs of points, lines, polynomials, circles and quadratics, graphing inequalities, slope, parallel and perpendicular lines, distance between points, midpoints and some conics.
- Plane Geometry: questions are mainly about angles, and the relationships among parallel and perpendicular lines, properties of circles, triangles, rectangles, parallelograms and trapezoids, transformations, volume and three-dimensional geometry.
- Trigonometry: a handful of questions are on basic trig functions, right triangles, graphing trig functions, solving basic trigonometric equations and using basic trig identities.

- Detail: questions that essentially ask you to find a detail in the text.
- Main Idea: questions that ask you to determine the primary message of a paragraph, section or entire passage.
- Comparative Relationships: questions that ask you to compare two or more people, viewpoints, events or theories.
- Cause-Effect Relationships and Sequence of Events: questions that ask you to determine what caused something else or what is the effect of something in the passage.
- Inferences/Generalizations: questions that require you to synthesize information and boil it down to a more concise form.
- Meanings of Words: questions that ask you to determine the meaning of a word in context.
- Author’s Voice, Method, or Purpose: questions that ask you to draw conclusions about the author’s point of view and method, basically how a passage is developed or its purpose.

- Detail: questions that ask you to find a specific data point on a graph, table, diagram, etc. and report the answer.
- Pattern: questions that ask you to predict a trend or relationship among the given data, generally by finding a point between existing data points or continuing to follow a trend beyond existing data.
- Inference: questions that ask you to draw conclusions from the data, sometimes combining information from multiple figures or experiments, and sometimes evaluating how new information would affect the experiment.
- Scientific method: questions that ask about how experiments are designed, or how experimenters test and interpret data.
- Compare and contrast: questions that only appear on the “Conflicting Viewpoints” passage and ask you to compare various aspects of opposing hypotheses on a scientific phenomenon, or explain how additional information might affect the various arguments presented.
