Academic Compatibility: A Breakdown of the SAT and ACT to Help You Choose a Test

Looking for a straightforward breakdown of the SAT and ACT sections to make it easier to choose which test is best for you? We've got you covered!

Please note that these comparisons are subject to change with the upcoming digital SAT format updates.  

Even with the recent evolution of test-optional college admission, both the SAT and ACT are great ways to showcase your college readiness. A high SAT or ACT score can help show colleges that you’re ahead of your peers. There are some distinct differences between the SAT and ACT. Both tests consist of two English and Language sections, but after that, they differ greatly. Here’s what you should know about all the major sections of these two exams to help you choose which one to take.

English and Language sections

The two English and Writing sections of the SAT and ACT are similar, with both sections testing reading comprehension in one section and grammar in the other.

Reading comparison

The Reading section of the SAT really puts your comprehensive skills to the test, whereas the ACT’s Reading section is much shorter and quicker paced.

  • SAT section: 52 questions
  • Time for completion: 65 minutes
  • ACT section: 40 questions
  • Time for completion: 35 minutes

Writing comparison

The SAT similarly inverts length with a shorter Writing section to balance out its longer Reading section. On the other hand, the Writing section of the ACT has significantly more questions than it does for Reading.

  • SAT section: 44 questions
  • Time for completion: 35 minutes
  • ACT section: 75 questions
  • Time for completion: 45 minutes

The Math sections

As mentioned above, the SAT has two Math sections, whereas the ACT just has one—we’ll talk about its extra section soon. Both SAT Math sections can be mostly completed without any higher-level math knowledge (i.e., calculus, statistics, etc.), but it may help to know basic math concepts in each of these subjects for both tests.

  • SAT section: 20 questions (no calculator); 38 questions (with calculator)
  • Time for completion: 25 minutes; 55 minutes
  • ACT section: 60 questions (with calculator)
  • Time for completion: 60 minutes

(This portion of the SAT exam is due for big changes with the digital update.)

The ACT STEM section

One section the ACT has that the SAT doesn’t is the Science section. It consists of a variety of scientific fields, including but not limited to biology, chemistry, and physics. There are around six to seven passages with five to eight questions pertaining to each. Each passage (sometimes paired passages) will go over a specific scientific concept, and the questions will ask for an analysis of the passage(s). Ideally, the broader your base of scientific knowledge, the better equipped you’ll be for this section.

  • ACT section: 40 questions
  • Time for completion: 35 minutes

3 ways to determine test compatibility

The SAT and ACT each hold their own advantages and disadvantages, so there’s no “best” test—rather, it’s about what fits better for you. The best thing you could do is take practice tests to see which one you prefer. High school students are limited on time and usually only sit for the SAT or ACT—rarely both—so you’ll have to analyze the exams against three things: your personality, your colleges of interest, and your prospective major.

Most colleges take both exam scores, but some will have a preference to one of the two tests. Be sure to do some research and see if you can determine which will look better to the schools you’re applying to. It also makes more sense to take a certain test if it fits your major better. For example, if you’re going into a math-heavy major, it would be smarter to take the SAT as it’s 50% math. On the other hand, if you’re going into a more science-based major, it would make sense to take the ACT since it actually tests for science. Finally, you should assess your own personality when picking between the two tests. If you’re a fast test taker who really doesn’t want to spend time thinking for long periods on questions or triple-checking your work, the ACT will be better for you. If you think you can’t do math without a calculator, the ACT will also be better for you. Based on the layout of the test and the way you learn best, you can pretty accurately determine which test you’ll do best on.

Recent test-optional policies have certainly changed the game of higher education, but the SAT and ACT can still put you ahead of your peers when your college applications are being reviewed. Take a hard look at these distinct differences between the exams, take some practice tests, then put your all into studying for great scores.

I have spent a lot of time aggressively searching for scholarships. It was a long and frustrating process until I found the CollegeXpress network. This site made my search so much easier. With the simple check of a few boxes, the site sorted out scholarships I was eligible for and led me directly to the correct websites. Winning this scholarship has definitely given me and my family some financial relief, and CollegeXpress has allowed me to improve my chances of winning further financial aid. Thank you so much!

CollegeXpress helped me find the school I am currently attending by consistently sending me emails of other schools. This allowed me to do research on other schools as well as the one I am in now!

CollegeXpress has helped me tremendously during my senior year of high school. I started off using the college search to find more information about the universities I was interested in. Just this tool alone gave me so much information about a particular school. It was my one-stop shop to learn about college. I was able to find information about college tuition, school rank, majors, and so much more that I can't list it all. The college search tool has helped me narrow down which college I want to attend, and it made a stressful process surprisingly not so stressful. I then moved to the scholarship search tool to find scholarships to apply for because I can't afford to pay for tuition myself. The search tool helped me find scholarships that I was eligible for. The tool gave me all the information I could ever need about a particular scholarship that was being offered. The CollegeXpress scholarship search tool is so much better than other tools offered, like the Chegg scholarship search. Thanks to CollegeXpress, I was able to apply to tons of scholarships in a relatively easy way!

Toward the beginning of last year, I was searching for scholarships to apply to through my school, town, websites online, and anything else I could find. I asked tons of questions [online] about scholarships and the best places to find them because I was desperate and needed as many as I could find. I came across a ton of bogus websites, but as soon as I found CollegeXpress, I knew I had to tell other people about it. It was definitely the most helpful site I came across, so I told my friends about it. CollegeXpress is definitely a website worth giving as a source.

CollegeXpress has helped me find scholarships for the colleges I applied to. It was very hard for me to find scholarships in the beginning that I was qualified for. My teachers recommended this website to find some, and not only did I find some scholarships but I also got to look into some schools I hadn’t heard of before. I was very happy to have discovered this website, especially with the coronavirus spreading all over as I can’t really go visit many colleges.
