Feeling nervous about the math portion of the ACT? You’re not alone! I have put together a study guide for you to use during your ACT Math practice sessions. You can use this with your tutor to identify your weak spots so you know where to focus. With that in mind, let’s start going over what information you need to know for successful ACT math practice.

What Do You Need to Know for ACT Math Practice?

Because the goal of the ACT is to measure your college readiness, you’re supposed to be well-prepared for it just by taking a good, college preparatory class schedule. And while that’s comforting to know, it’s not really helpful if math isn’t your best subject or if you’re struggling with this section during your ACT math practice sessions.

There are about 31 formulas you should know when you take the ACT math section. Check out this link for the formulas and for a free study session to help you master them.

ACT Math Practice Materials

So now that you know what will be covered on the math section, let’s go over where you can find study materials to help prepare you for when you sit down to take the exam.

**Free ACT Math Practice Materials**

Who doesn’t love free stuff? The good news is you don’t have to spend a fortune obtaining quality practice materials. Here are some ideas for getting access to free test prep materials.

The Official ACT Website

In addition to signing up for the ACT and getting your results online, the official ACT site also provides you with 60 sample math questions. With each question comes feedback on each answer choice to help you understand why the option is either correct or incorrect.

ACT Practice Tests

Because these give you an authentic test-taking experience, you need to add them to your ACT math practice materials. This will help you prepare the best for the ACT. Below, I’ve provided links to the available practice tests.

Your Local Library

Sounds crazy right? If you aren’t sure which of the test prep company books to go with, check out your local library. Most libraries carry a variety of test prep books and have a copy machine. You can easily make copies of the math sections and use them as much as you want.

Conclusion

By investing your time in quality ACT math practice, you can improve your ability to do well and score well on the test. Use this guide as a starting point and find a top-scoring tutor to help you prepare to the best of your ability. There’s no reason to fear the math section of the ACT!
