ACT Practice Questions — Study Guide
Free, topic-by-topic study notes for the ACT Practice Questions exam. Read a chapter, then practice it.
English — Grammar & Usage
The ACT English section rewards clean, standard written English. This chapter covers the grammar and usage rules most often tested: subject-verb agreement, pronoun case, verb tense and form, and modifier placement. These are self-contained skills you can practice one sentence at a time.
English — Punctuation & Rhetoric
Beyond grammar, the ACT tests punctuation and rhetorical skill: choosing the wording that is clear, concise, and correctly punctuated. This chapter covers commas, semicolons, colons, apostrophes, and the ACT's strong preference for concise phrasing.
Math — Algebra
Algebra questions ask you to solve equations, evaluate functions, work with proportions and percents, and interpret linear relationships. Every item here is self-contained: read carefully, set up the equation, and re-check by substituting your answer back in.
Math — Geometry
Geometry questions test core formulas for area, the Pythagorean theorem, circles, and polygon angles. Memorizing a small set of formulas and reading each figure carefully lets you solve these quickly and accurately.
Science Reasoning Basics
ACT Science is a reasoning test, not a memorization test. This chapter uses tiny inline data tables so you can practice the core skills: reading trends, extrapolating from a pattern, and identifying variables in an experiment, without any long passage.
