SAT® or ACT®: which should you take?
Both tests are accepted by U.S. colleges that ask for a score, and both reward the same core reading, writing and math. They differ in pace, structure and scoring. Here is an honest side-by-side, then the fastest way to find out which one suits you.
Side by side
| Digital SAT | Enhanced ACT | |
|---|---|---|
| Sections | Reading and Writing; Math | English, Math, Reading; Science optional |
| Questions | 98 (54 Reading and Writing, 44 Math) | 131 (50 English, 45 Math, 36 Reading), plus 40 Science if you take it |
| Testing time | 2 hours 14 minutes | 2 hours 5 minutes, or 2 hours 45 minutes with Science |
| Time per question | About 71 seconds in Reading and Writing, 95 in Math | About 42 seconds in English, 67 in Math and Reading, 60 in Science |
| Adaptive? | Yes: Module 1 decides whether Module 2 is harder or easier | No: everyone on a form gets the same questions |
| Calculator | Allowed on every Math question, with a graphing calculator built into the test app | Allowed on Math only |
| Answer choices | 4 (some Math answers are typed in) | 4 on every question |
| Scores | 200–800 per section, 400–1600 total | 1–36 per section, Composite 1–36 from English, Math and Reading |
| Wrong answers | No penalty | No penalty |
| How you take it | On a device, in a test app | Online at a test center or on paper (U.S. national dates) |
How they feel different
- Pace. The ACT asks for more questions in less time, especially in English. If you read quickly and decide fast, that suits you; if you like to check every answer, the longer time per question on the SAT may.
- Reading. SAT Reading and Writing questions each come with one short passage. ACT Reading uses longer passages with several questions each, and English questions point to underlined parts of an essay.
- Math. SAT Math leans on algebra and data, with a calculator throughout. ACT Math covers a wider spread, including more geometry, trigonometry and topics like matrices and vectors.
- Science. Only the ACT has a Science section, and it is optional. It is about reading data and experiments more than remembering facts. Charts and data appear on the SAT too, inside its other sections.
- Adaptivity. On the SAT, Module 1 matters most because it sets your route. On the ACT every question counts toward the same scale whatever came before.
Comparing scores
ACT and College Board publish a joint concordance that matches ACT Composite scores to SAT total scores. Use the official tables at the ACT/SAT concordance page on act.org; we link to them instead of copying them, because only the official version is kept current.
How to decide
- Take a diagnostic for each test. It shows your level in every area, with no full test needed.
- Compare where you start. Look at your levels and how the pace felt. A clear gap is your answer.
- Check your dates. Pick the test whose dates give you enough time to prepare: SAT test dates and ACT test dates.
- Commit to one. Preparing well for one test usually beats preparing halfway for both.
Questions
Do colleges prefer the SAT or the ACT?
Colleges in the United States that ask for a test score accept either one and don’t favor one over the other. Check each college’s own testing policy, since some are test-optional and some require a score.
How do I compare an SAT score with an ACT score?
ACT and College Board publish a joint concordance that matches ACT Composite scores to SAT total scores. Use their official tables on act.org rather than a copy, because only the official tables are kept up to date.
Should I take both tests?
Most students do best by picking one and preparing well for it. Take a diagnostic for each first; if one clearly suits you, put your time there.
Is the ACT Science section a science knowledge test?
Mostly not. It asks you to read tables, graphs and experiments and reason about them. Some questions draw on introductory science, and the section is optional on the enhanced ACT.
