Mathematics
ACT Math Section
The ACT math section is 60 questions in 60 minutes — a question every minute. It tests pre-algebra, algebra, geometry, trigonometry, and a small amount of advanced topics. Pacing is the hard part: fast accurate test-taking matters as much as content mastery.
How to Approach ACT Math Section
Cover the six content areas
Pre-algebra (~24%), elementary algebra (~17%), intermediate algebra (~15%), coordinate geometry (~15%), plane geometry (~23%), trigonometry (~7%). Plane geometry weighs more than on the SAT.
Master pacing
60 questions in 60 minutes means one minute each. Easier questions (first 20-25) should take 30-45 seconds — bank time for the harder back-third. Skip and return if stuck more than 90 seconds.
Strategy: plug in numbers
When a question has variables in the answer choices, pick simple numbers (avoid 0, 1, and numbers in the problem), plug into the original, then test each answer choice. Often faster than algebra.
Frequently Asked Questions
How is ACT math different from SAT math?+
ACT has more plane geometry, includes trigonometry, allows calculator on every question, and is faster-paced. SAT math has more algebra emphasis and a no-calculator section.
What calculator should I use?+
Any approved scientific or graphing calculator. TI-84 is the most common for graphing. The ACT doesn't require a graphing calculator — a scientific calculator is enough — but knowing your tool well matters more than which tool.
What's a good ACT math score?+
ACT subscores are 1-36. 30+ is competitive for most colleges; 33+ for top-tier. Average is about 21. The math section often determines whether someone clears a school's middle-50% range.
