# ACT Math: Everything You Need to Know

Bonus Material: PrepMaven’s ACT Guidebook

ACT Math is the second section of the ACT. It comes right after ACT English, and it’s a long one — students have 60 minutes to answer 60 questions.

Timing can definitely be a challenge on this section for that reason. What’s more, ACT Math is 100% content-based, which mean that test-takers do have to know things like the Pythagorean Theorem, trigonometry, probability, and other foundational math topics.

What do you need to know about Math on the ACT? What math concepts in particular does this section test? And what can you do to improve your score?

As the test prep experts, we’ve got the answers to these questions — and much more!

Plus, we give readers access to our ACT Guidebook, a comprehensive guide for students navigating the test for the first time. It’s free and you can grab it below!

## 1) ACT Math in a Nutshell

Here’s what ACT, the organization that produces the test, says about the math section:

The ACT mathematics test is designed to assess the mathematical skills students have typically acquired in courses taken up to the beginning of grade 12. The test presents multiple-choice questions that require you to use reasoning skills to solve practical problems in mathematics. The material covered on the test emphasizes the major content areas that are prerequisites to successful performance in entry-level courses in college mathematics.

What does this actually mean?

In simpler language, ACT Math tests the math subjects most students will have learned through their senior year in high school. That includes pre-algebra, Algebra 1 and 2, geometry, trigonometry, and advanced math.

In fact, the test heavily emphasizes subjects from Algebra 1 and 2, which is why we encourage students to take the test only after they’ve completed Algebra 2.

Of course, ACT Math is not like your typical high school math test. We like to say that it tests familiar math concepts in unfamiliar ways. That’s what ACT is getting at when it says the questions “require you to use reasoning skills to solve practical problems.”

For example, here’s a typical ACT word problem from an official practice test:

This question might look intimidating at first glance, because there are a lot of words and numbers! But hiding behind all those words and numbers is a single concept: representing linear equations.

Let’s take a look at the format of ACT math next.

### Format

ACT Math is the second section of the test, appearing right after ACT English and before ACT Reading.

There are 60 questions on this section, to be completed in 60 minutes. These questions are arranged generally in order of increasing difficulty, which means that questions 1-20 are approximately low-difficulty, 21-40 are medium-difficulty, and 41-60 are high-difficulty.

Of course, “difficult” is a relative term on the ACT! It’s not uncommon for a student to find question #10 difficult, for example, and question #55 easy.

That’s why it’s so important to establish your own strengths on ACT Math, which you can do by taking a practice test.

While the questions on ACT Math generally get harder as they progress, the concepts typically tested can appear in any order. For example, #18 might be a trigonometry question, while #40 might test pre-algebra, but in a harder way.

Take a look at this question from the first half of a practice test. It’s a problem about trigonometric functions, but in a less complicated way:

Now compare this question from the end of a practice test. It’s also a problem about trigonometric functions, but it’s more complex!

Students are allowed to use a calculator on ACT Math, which is important. Using a calculator can be very helpful for preventing careless errors, checking your work, and tackling harder questions! Find ACT’s calculator policy here.

### Scoring

How is ACT Math scored? Every section on the ACT is scored on a scale of 1-36. So, 1 is the lowest score you can earn on this section and 36 is the highest score.

The test graders calculate this based on section-specific algorithms that boil down to converting your raw score (the number of questions you get right) to a number between 1 and 36.

All ACT section scores are averaged to generate a composite score on a scale of 1-36. You can find out more about how this works in our ACT scoring guide.

There is no wrong answer penalty on the ACT. This means that you don’t lose points for getting a question wrong on Math — you simply do not get any points. Students can use this to their advantage by never leaving a question blank on this section!

How many questions do you have to get right in order to achieve a high score? The answer: it depends.

Even though the ACT is a standardized test, no two Math sections are the same in terms of difficulty and content. A 30 on one Math section likely doesn’t equate to a 30 on another.

The key to improving your ACT Math score thus lies in maximizing your raw score — the more questions you ace on this section, the higher your odds are of earning a competitive score.

We’ll talk more about how to improve your Math score later on in this post. If you want more insight into what counts as a “good” ACT score overall, check out our other post on the subject.

### The Math You Need to Know for the ACT

So what math do you actually need to know for the ACT?

ACT outlines three broad categories of math content areas tested on this section:

• Preparing for Higher Math (~60% of all questions)
• Integrating Essential Skills (~40% of all questions)
• Modeling (~25% of all questions)

However, because these concepts are pretty broad (especially that Modeling category!), we’ve broken them down even further below based on our analysis of official ACT practice tests.

## How to Improve Your ACT Math Score

What can you do to improve your ACT Math score? Start with these five strategies, and then check out these 10 ACT Math Strategies to Get a High Score.

### Strategy #1: Prioritize easier questions.

On each section of the ACT, every question is worth the same number of points. This means that an “easy” question is worth just as much as a “hard” question.

This can be counterintuitive, because many students are used to hard math questions being worth more on exams! They race through the easy questions on standard high school tests so they can spend most of their time on the more difficult problems.

However, this approach will not serve you on ACT Math.

Prioritize easier questions first and make sure you feel 100% confident on those before proceeding to difficult questions. This typically means spending most of your time on questions 1-40 on ACT Math.

If you find yourself spending more than a minute working a problem, skip it and come back. Save any remaining time at the end of the test for double-checking your work on those early questions.

### Strategy #2: Make the answers work for you.

Take a look at this sample ACT Math word problem:

Do you see how all of the answers are in number form? If the answer choices are all numbers, this is a good sign that you can make those answers work for you instead of diving into complicated algebra!

You can “plug in” the answers to the problem and see which one fits the stipulations of the question. This is a much easier and faster way of solving this word problem.

Remember: on ACT Math, it doesn’t matter how you arrive at the right answer, because no one’s grading you on your work. For that reason, choose the most efficient and easiest way of getting to that correct answer.

### Strategy #3: Replace abstract values with concrete ones.

ACT Math loves to ask questions that contain variables or unknown values, like “x”, “3x+2”, “|x| – x”, etc…

It is always a lot harder to work with abstract values as opposed to concrete ones. So replace those abstract values with actual numbers!

In the example question above, that would mean replacing “negative real value of x” with something like -4. Then, plug your chosen value of x into the answer choices to see which ones are true and which ones aren’t.

When picking numbers in this way, be sure to choose ones that are relatively small and easy to work with, but avoid using 1, -1, or 0.

### Strategy #4: Cut through the fluff on word problems.

ACT Math contains a lot of word problems! These can be tricky to navigate, because they’re often very wordy and do a great job of hiding the actual math involved — and the question itself.

When approaching these word problems, try to separate the “fluff” — stuff you don’t need — from the actual problem. Identify what the question is truly asking and focus on that.

This word problem is a great example of this. There are a lot of words here, but what is the question really asking?

If you realized that this is really asking what what’s the smallest number that’s divisible by 5, 6, and 7 — you’re right! (Then, once we have that number, we need to divide it by 7.) This really has nothing to do with relay races, grades, or groups of students.

The actual math involved in this word problem is pretty basic, but ACT Math loves to mask that in complicated wording.

### Strategy #5: Build a solid foundation of content knowledge.

ACT Math and ACT English are the two sections of the test that rely most heavily on outside content knowledge. (Reading and Science are basically 100% strategy-based.)

For this reason, a solid foundation of content knowledge can only serve you on ACT Math!

Because a lot of this content covers algebra and geometry, topics many test-takers study earlier on in high school, it’s important to review any topics you’re rusty on.

You can pinpoint what you need to review by taking a practice ACT.

Keep in mind that the ACT does not include a reference page with relevant math formulas before the Math section. You’ll have to go into the test with those memorized, so make sure to use flashcards or other study tools to lock those formulas in place!

These are only a handful of our expert ACT Math strategies. Find even more in this post here.
