ACT test vs. SAT: Sections and content

Both the SAT and the ACT involve similar subjects in reading, language comprehension, and mathematics. More than finding out what you know, the aim is to understand your ability to comprehend information, think critically, and solve problems. Let’s go over what you can expect from each test section.

SAT sections

The SAT is formatted into two sections that measure your ability to read and comprehend information as well as complete a series of math-based questions. You’ll find that both sections have two modules, and you’re allowed to use a calculator for both math modules.

• Reading and Writing: Reviewing and analyzing passages

• Math: Algebra, advanced math, problem-solving and data analysis, geometry, and trigonometry

ACT sections

The ACT has a total of three required sections, with optional science and writing sections. Like the SAT, you’re being tested on your ability to understand information, think critically and logically (in the case of the science section), and complete math questions.

• English: Grammar, punctuation, sentence structure, and rhetoric

• Math: Algebra, geometry, functions, and statistics

• Reading: Review and analyze passages

• Science (optional): Interpret data, analyze experiments, and evaluate validity

• Writing (optional): Writing skills

The SAT tends to be a bit more math-heavy, while the ACT incorporates a science section that seeks to understand your logical and critical thinking abilities by asking you to review passages with graphs, charts, and other data. The SAT and ACT let you use a calculator for all math questions.

Do colleges prefer ACT or SAT?

While most colleges accept ACT and SAT scores, some schools might have a preference for one test over the other. Generally, however, colleges and universities accept either test score. It’s best to research your desired schools and determine what, if any, testing preferences they have. Doing so may help guide your standardized test selection as you prepare your college applications.

ACT exam vs. SAT: Questions and length

It takes a little over two hours to complete the SAT, which does not include the mandatory breaks between some tests. Here’s how each SAT section breaks down [2]:

It takes two hours and 45 minutes to complete the ACT, and you take mandatory breaks between some of the tests. Here’s how each ACT section breaks down [3]:

SAT vs. ACT score comparison

The SAT and ACT have different scoring mechanisms: the SAT is a total score between 400 and 1,600, while the ACT is a composite score out of 36 [4, 5]. Here’s how the two exams break down their scoring.

SAT scoring

Your SAT score reports include two types of scores, which include your total and section scores:

• Total score: This figure ranges from 400 to 1,600 and represents the sum of the two section scores: Reading and Writing (RW) and Math [4].

• Section scores: Section scores for RW and Math range from 200 to 800 [4]. SAT considers an RW score of 480 or higher and a Math score of at least 530 as college-ready [6].

The SAT does not penalize students for incorrect answers. This means there is no penalty for guessing, and you may answer every question even if you are unsure.

ACT scoring

Your ACT composite score is the average of the four test scores: English, Math, Reading, and Science, which is rounded to the nearest whole number, between one and 36.

If you opt to complete the essay portion of the ACT, you’ll receive an overall score of two to 12 and four separate domain scores, each ranging from two to 12, that have to do with Ideas and Analysis, Development and Support, Organization, and Language Use and Conventions [7].

College and career readiness scores vary across the ACT’s test sections [8]:

• English: 18

• Math: 22

• Reading: 22

• Science: 23

Like the SAT, the ACT does not penalize test takers for incorrect answers. You can guess even if you are not sure about the answer without losing points.

Why take ACT vs. SAT? 

Historically, the vast majority of colleges and universities in the US required the SAT or ACT as part of their admissions process. However, some schools have now adopted a test optional policy, meaning you do not have to take either exam.

That being said, not every school has a test-optional policy, so reviewing the application requirements for every college or university you’d like to attend is best. If you have the option to decide whether to take the SAT or ACT, there are other reasons why you might want to take either standardized test and submit your scores:

• Bolstering your admissions portfolio: If you submit test scores, admissions officers will consider them alongside the rest of your application materials to develop a well-rounded idea of your interests, strengths, and the type of student you are. Submitting your scores may enhance your application if you score in the top 50th (or even better, above the top 25th) percentile compared to previously admitted students.

• Accessing classes that fit your educational needs: Admissions committees may use test scores to decide which courses you should take if the school offers different levels, like developmental and honors.

• Qualifying for merit scholarships: Some scholarship organizations use test scores to identify potential candidates for their merit-based programs. Your exam scores can add insight into your academic strengths and potential.

• Keeping your options open: Having test scores ready to submit as part of your application will keep your options open, even if your first choice of school is test optional. You may change your mind and want to apply for a school with a testing requirement.

Who should take ACT vs. SAT? 

Before you set about studying for and taking either the SAT or ACT, it may help to take free practice tests online and see how you feel about completing each one with little to no preparation. That can be a good indication of how you’ll do with additional study time.

Some additional factors that may help you determine which test is for you are:

• Number of questions: The ACT has 171 questions compared to the SAT’s 98 questions [1, 2].

• Subject strength: While the SAT and ACT subjects are similar, there are notable differences. Think about which subjects you enjoy and do well in. If math is not your strong suit, consider that you have access to a graphing calculator and formulas in the SAT platform on test day. If you do well in science, the ACT has a section that might be worth your time.

• Availability: Your area may have different test centers and scheduling for each test. You can get an idea about when each test is available to take by visiting The College Board’s website or the ACT’s test center site.

• Cost: It costs $68 for the SAT or the ACT [9, 10]. If you choose to complete the ACT’s optional writing section, that cost rises to $93 [10]. These prices don’t include additional fees like late registration or cancellation.

If you’re still unsure which test is right for you, consider taking both of them officially and see if you do better on one than the other. You can submit your higher score as part of your college application.
