11 ACT Math Tips You Need To Know

Even if Math is your least-favorite subject, you can still ace the ACT Math test, through hard work and the right problem-solving strategies.

To ace the Math test, you need to memorize important equations and formulas, problem-solve step-by-step with pencil and paper, prioritize your time, and take lots of practice tests before exam day.

More details on these Math test strategies below. For even more expert help on the Math test, consider taking an ACT prep course with Prep Expert.

Memorize Important Equations & Formulas

Have important equations and formulas like the quadratic equation and Pythagorean theorem memorized before exam day.

Even though the ACT provides you with some of them on the first page of the Math test, you should have all the important equations and formulas memorized:

  • Equation of a line
  • Quadratic equation
  • Equation of a circle
  • Pythagorean theorem

Having them down pat will leave you confident in your problem-solving abilities, and prevent you from wasting time flipping back and forth between the problems and the first test page.

So, take the time to make up some flashcards, and drill these equations and formulas until you know them by heart.


Write Out Your All Problem-Solving Steps

Do your problem-solving with pencil and paper, writing out all the steps as you work toward an answer.

If you’re a self-styled math whiz or addicted to your calculator, you might not write much in your exam booklet while working your way through the Math test.

However, writing out all your problem-solving steps prevents you from making simple mistakes.

Common mistakes include:

  • Entering the wrong number into your calculator
  • Giving the answer for x when you’ve been asked for 2x.

This pencil and paper approach also leaves work for you to check, if you finish the test early and have the opportunity to review your answers.


Use Your Calculator To Check Your Work

Don’t be dependent on your calculator for problem-solving—just use it to check your work.

As mentioned, with pencil and paper, you’ll solve problems with confidence, and complete the test with greater speed and accuracy.

Your calculator is a great tool for checking your work. But if you use it as a substitute for detail-conscious, step-by-step problem-solving, it can be counterproductive.


Not to mention, there’s always the risk your battery dies in the middle of the exam. Don’t set yourself up for this nightmare scenario!

Be Sure Your Calculator Is Allowed

Check the ACT website before the exam to ensure your calculator is permitted.

You won’t be able to use your smartphone as a calculator, or a calculator that makes noise. Most of the Texas Instruments (HI) calculators used in high school Math classes are allowed.

However, some of the more advanced versions might not be—so it’s best to double-check. Also, it doesn’t hurt to have a backup battery for exam day!


Don’t Rush On Easy- and Medium-Level Difficulty Problems

All the problems on the Math test are worth the same number of points. Don’t rush on easy- and medium-level difficulty problems to finish the test on time.

Many students think they have to finish the entire Math test before the 60 minutes are up, without guessing on any questions. However, problems on the Math test get more difficult as you progress.

Students tend to rush through the easier questions, so they have more time  to tackle the tougher ones. But there’s a problem with this strategy, particularly for students who aren’t great at Math.

Working too quickly at the beginning of the Math test can cause you to make a lot of simple mistakes—and get lots of questions wrong. Then—even though you have more time left—you get even more questions wrong because you can’t answer the more advanced problems correctly.

The sum total of this approach: lots of lost points.

A better approach, particularly if you’re looking for a big test score improvement, is:

  • Take your time at the beginning of the test
  • Make to answer as many of the first 40 problems correctly as possible

Remember: all the problems on the test, regardless of their difficulty, are worth the same number of points.

You should still have enough time to dig into some of the remaining 20 questions, but the last 10 questions are extremely difficult.

Most students get them wrong anyway. So, if you’re gonna guess, you might as well guess on these ones.


Wear A Wristwatch To Keep Track Of Time

Wear a wristwatch to pace yourself and track your problem-solving progress.

If you’re hoping to get a 36 on the Math test, you’ve got to solve all of the problems correctly. That means you need to leave yourself enough time to finish.

You should budget:

  • 30 minutes to answer the first 40 questions
  • 30 minutes to answer the last 20 questions

While there will be a clock in the test center, and your proctor will make time announcements, it’s best to have a wristwatch to keep your own time.

This way you can ensure you keep the right pace, and make the progress, you need to finish the test on time.



Skip Over Problems You Can’t Solve

If you haven’t made any progress on a problem after 10 seconds, circle it and move on.

If you’re baffled by a tricky problem and know only one step you can take—say, factoring, or combining like terms—take that step, and see if it opens the problem up for you. If it doesn’t, circle the problem number and move on.

Fixating on a vexing problem wastes time and is extremely anxiety-provoking, dragging down your performance on the rest of the test.


Try Plugging The Answer Choices Back Into The Problem

If you’re stuck, try inserting the answer choices back into the problem and see if one of them works.

This trick doesn’t always work, but if it does—there’s your answer! When doing this, make sure to plug in all the answer choices, to be sure you haven’t made a mistake.

Remember, this is something you should do as a last resort—because it’s so time-consuming, it’s not a great first problem-solving step.

Don’t Be Intimidated By Advanced Math Topics

Even if you have trouble with Math in school, you’ve probably already learned the most advanced topics covered in the ACT—with some solid studying, there’s no way you can’t handle ‘em.

The most advanced Math on the test is limited to some basic trigonometry problems. So, if you’re in Precalculus or higher-level Math now, you likely already have a good handle on all the Math you’ll.

If you haven’t learned any trigonometry yet, don’t worry—none of the concepts are too difficult to learn on your own.


Complete Lots Of Practice Tests

The more practice tests you complete before exam day, the higher you’ll score.

Even if you’re not so great at Math, if you take lots of practice tests, you’ll acquire enough familiarity with the topics covered, and the best (and quickest) approaches to solving problems, to put yourself in a position to score a 36 on the test.

Of course, if you don’t like Math, the test will still be a slog, and there will always be a question or two here and there that proves particularly tricky.

But, there’s truly no ceiling on your Math test score, regardless of how you’re doing right now if you’re willing to work hard.
