ACT Prep Study Guide
Maximize your ACT composite score with targeted AI study tools and practice from your ACT prep materials.
The ACT tests English, Mathematics, Reading, and Science, with an optional Writing section. Unlike the SAT, the ACT is more curriculum-based — it rewards content knowledge alongside reasoning skills. The Science section, which is unique to the ACT, tests data interpretation and scientific reasoning rather than specific science content knowledge, but familiarity with basic scientific concepts and graph interpretation is helpful.
The English section tests grammar, punctuation, and rhetorical effectiveness — the 75-question section tests clarity of expression, concision, and correct usage of commas, apostrophes, subject-verb agreement, and parallel structure. The ACT English moves quickly (9 minutes per passage), so automaticity with grammar rules is essential. Building pattern recognition for each grammar rule through consistent practice reduces the need for slow deliberate reasoning under time pressure.
The ACT Math section covers pre-algebra, algebra, coordinate geometry, plane geometry, trigonometry, and some statistics. The 60-question section allows 60 minutes — exactly one minute per question — which is manageable for students who are comfortable with the content. Trigonometry (approximately 7-10% of questions) is tested more prominently than on the SAT, and basic trigonometric identities and the unit circle deserve specific preparation.
The Science section tests interpretation of scientific data presented in graphs, tables, and figures, comparison of scientific experiments and hypotheses, and evaluation of conflicting scientific viewpoints. The most effective preparation is practicing systematic figure reading: identify what each axis represents, what relationships the data shows, and what conclusions it supports and does not support. Clario generates practice questions from your specific ACT prep materials targeting your weak sections.

Frequently Asked Questions About ACT Prep
Is the ACT easier than the SAT?
Neither test is objectively easier — they test partially different skills and some students score significantly higher on one than the other. The ACT is more curriculum-based with a Science section that has no SAT equivalent. The SAT has fewer questions overall but more complex reading passages. Taking official practice tests for both and comparing scaled scores is the most reliable way to determine which test plays to your strengths.
What is the ACT Science section testing?
The ACT Science section tests scientific reasoning and data interpretation, not specific science content knowledge. It presents data in tables, graphs, and figures from scientific experiments and asks students to identify relationships, interpret data, compare experimental results, and evaluate scientific hypotheses. Strong performance requires careful reading and data interpretation skills more than memorized science facts.
