SAT or ACT?
Parents and students start the college process by comparing the SAT and ACT tests. The SAT and ACT cover generally the same topics, and both scores are used for college admissions decisions and the awarding of merit based scholarships.
In the past, schools on the coasts generally gravitated towards the SAT while those in the midwest preferred the ACT. Now, however, the college application landscape has changed and schools have become increasingly flexible; both tests are now widely accepted across all US colleges.
Don’t let the question of SAT or ACT keep you up at night! Know the basics about each test, your strengths and weaknesses as a test taker, and focus on!
Comparing the SAT and ACT:
The ACT has a Science section and the SAT does not, but on the ACT Science is now optional.
The SAT is fully digital and adaptive. You take it in the Bluebook app, and a calculator is allowed on every math question.
| Aspect | SAT | ACT |
|---|---|---|
| Why Take It | Colleges use SAT scores for admissions and merit-based scholarships. | Colleges use ACT scores for admissions and merit-based scholarships. |
| How You Take It | Fully digital. You test in College Board’s Bluebook app on a laptop or tablet, at a test center. | Paper or online at the test center, depending on the date and the site. |
| Test Structure | Reading and Writing, then Math. Each section is split into two modules. | English, Math, Reading, then optional Science. Optional Writing comes last. |
| Length | 2 hours, 14 minutes plus a 10-minute break | 2 hours, 5 minutes for the three core sections. 2 hours, 45 minutes if you add Science. Writing adds another 40 minutes. |
| Adaptive? | Yes. How you do on the first module of a section decides whether the second module is harder or easier. | No. Every student sees the same questions in the same order. |
| Reading | Short passages, usually a paragraph, with one question each, mixed in with the grammar questions. | 36 questions across four passage sets. |
| Science | None as its own section, though charts and data show up inside Reading and Writing and Math. | Optional since 2025. 40 questions in 40 minutes, testing how you read experiments, charts and tables rather than science you memorized. |
| Math | Algebra, advanced math, problem solving and data analysis, plus a smaller slice of geometry and trigonometry. | Algebra, geometry, trigonometry, probability and statistics. |
| Calculator Policy | Allowed on every math question. Bluebook has a Desmos graphing calculator built in, or you can bring your own approved one. | Allowed on every math question. |
| Formula Sheet | Provided, and you can pull it up on screen at any point during Math. | Not provided. You memorize your formulas. |
| Essay | None. College Board discontinued the SAT Essay in 2021. | Optional Writing test, scored 2 to 12. It does not count toward your composite. |
| How It’s Scored | Scored on a scale of 400 to 1600, with each of the two sections worth 200 to 800. | Composite of 1 to 36, which is the average of English, Math and Reading only. Science is reported separately and pairs with Math for a STEM score. |

Here’s an interesting analogy comparing the two tests:
The ACT is like lifting a 5 pound weight ten times while the SAT feels like lifting 25 pound weights twice. Both are quite draining, but in different ways. The ACT is extremely fast paced while the SAT requires you to think more and deeply.
Important note: Be sure to look carefully at admission preferences and requirements to double check which of the tests your prospective college accepts.
According to the College Board, while both tests measure what you learned in high school, the SAT is a better indicator of skills you will actually need to succeed in college and beyond. Instead of focusing on how well you can recall information, the SAT emphasizes one’s ability to apply it in real world scenarios. This is why the SAT provides everyday math formulas while the ACT expects you to memorize them.
Test Format
| Structure and Timing | SAT | ACT |
|---|---|---|
| Testing time | 2 hours, 14 minutes | 2 hours, 5 minutes core. 2 hours, 45 minutes with Science. Add 40 minutes for optional Writing. |
| Structure | 2 sections, 2 modules each | 3 core sections, plus optional Science and optional Writing |
| Number of questions | 98 | 131 core, or 171 with Science |
| Time per question | About 1 minute, 22 seconds on average | About 57 seconds on average |
| Score range | Composite 400 to 1600, with Reading and Writing and Math each 200 to 800 | Composite 1 to 36 from English, Math and Reading. Science and STEM scores reported separately. Writing domain scores 2 to 12. |
| Section length and timing | Reading and Writing: two 32-minute modules of 27 questions each, so 54 questions in 64 minutes. Math: two 35-minute modules of 22 questions each, so 44 questions in 70 minutes. | English: 50 questions in 35 minutes. Math: 45 questions in 50 minutes. Reading: 36 questions in 40 minutes. Science (optional): 40 questions in 40 minutes. |

Test Timing
The SAT gives you 98 questions and the ACT gives you 131 in its three core sections, so timing is one of the most important things to weigh when you pick a test. You get roughly 1 minute and 22 seconds per question on the SAT and roughly 57 seconds per question on the ACT. The gap used to be wider, because the shorter ACT introduced in 2025 cut the question count without cutting the time by as much. Reading in particular went from about 53 seconds per question to about 67.
One more thing worth knowing before you choose: the SAT is adaptive, so the second module of each section adjusts to how you did on the first. The ACT is not. If you like the idea of a test that meets you where you are, that is a point for the SAT. If you would rather see a fixed test you can practice against exactly, that is a point for the ACT.
A little bit stressed out?
I feel you. Test taking is honestly one of the worst things about the college process in my experience. We love spending summertime huddled over practice tests and test prep books and watching everybody else have fun. Are you feeling this FOMO? Do you find yourself “reading” through grammar rules only to realize that you’ve actually just been looking at the words and not processing anything? It happens to the best of us. Want to crush the ACT or SAT in the next few weeks? We got you. Prepmedians teaches ACT and SAT test prep through entertaining and engaging ways with sketch comedy, music, rap, and more. We’ll get you through those boring summer study days in no time. Check us out today!
