Are you preparing for the ACT? You’re probably wondering what you need to know to be ready for the math section. For many students, the math section can be the most stressful part of the ACT because of its breadth and time difficulty.
In this post, we'll break down exactly what will appear on the ACT math test, with sample questions. We'll also give you the resources you need to start studying so you can get the best score possible.
What's the Format of the ACT Math Section?
The ACT math section is 60 minutes long, with 60 questions total – so you’ll have just one minute to complete each question. You’ll definitely have to work quickly if you want to answer each one! Every question is multiple choice, and there is no penalty for guessing.
Pacing and problem solving are the big challenges on the ACT math section. Pacing is tricky because you have to answer questions as quickly as possible without losing accuracy. In addition, you have to be able to quickly identify ways to solve problems. This is why studying specifically for ACT math is so important, since it requires you to work faster and more strategically than you have to in math class.
You need to be able to problem solve, or use what the ACT calls using reasoning abilities. In addition, the math questions are not ordered by topic, so you need to be prepared to quickly switch between topics like statistics, algebra, and geometry.
Test Content and Requirements
The ACT tests math skills that most students know by the beginning of grade 12 – which in practice means nothing beyond Algebra II. If you’re an advanced student, ACT math content will be very straightforward.
The content breakdown for ACT math is:
- Pre-Algebra (20-25%)
- Elementary Algebra (15-20%)
- Intermediate Algebra (15-20%)
- Coordinate Geometry (15-20%)
- Plane Geometry (20-25%)
- Trigonometry (5-10%)
We’ll explore those sections in-depth with example problems and explain how you get scores for each section.
You can use a calculator – but it has to be a permitted one. However, you’re not required to use a calculator, meaning all problems on the ACT can be solved without one. Be careful not to rely too much on your calculator if you use one, as it can actually slow you down. (For an expert discussion on the best calculators for standardized tests, see our post.)
Unlike the SAT, you’re not given a reference sheet, so you have to know basic math formulas (y = mx + b, the area formula, the quadratic formula, etc) but nothing too complex.
What Are ACT Math Section Subscores?
Your score is based on how many total points out of 60 possible you earn. That raw score is converted to a section score between 1 and 36 (for more on that process, see our ACT scoring guide).
You also receive three subscores based on the six content areas: pre-algebra and elementary algebra, intermediate algebra and coordinate geometry, and plane geometry and trigonometry. The subscores basically give more detailed information about your performance, but are generally not looked at too closely by colleges (your overall math section score and ACT composite are most important).
However, you can use the subscore areas to focus your studying by math topic. We will explore the three math subsections and show some example questions for each. You might find that you are more than prepared for one area but need to focus your practice on one topic, like trigonometry or coordinate geometry.
While we will give a detailed overview of what you can expect to see on the math section, we also recommend doing full practice tests so you can really get a sense of what the ACT math section is really like.

Where Can You Find ACT Math Practice Materials?
Now that you know what's on ACT Math, your next step is to start practicing! The most important way to prepare for the ACT is to take practice tests. We have links to free, official online practice tests to get you started. If you need to especially practice math, you can just take the Math sections, but for everyone we recommend you take at least a few full-length practice ACTs so you can get an idea of how well you'd do on the entire exam and get experience taking such a long test.
A prep book can also be a major help while you're studying ACT Math, especially if there are some concepts you're still struggling to understand. However, it's important to get a high-quality prep book. See our guide to the best ACT prep books on the market.
