ACT vs SAT: Which Test Should You Take?
By Sana Iqbal · · 7 min read
Quick answer
US universities accept the ACT and SAT equally, so take whichever suits you. The ACT includes a science-reasoning section and gives you less time per question, rewarding speed and confident reading. The SAT is digital and adaptive, with more time per question and a heavier emphasis on evidence-based reasoning. Take a timed practice test of each and let your scores decide.
Universities genuinely do not prefer one
Every US college that requires a test accepts both, and none gives a preference. This surprises students who assume the SAT carries more prestige on the coasts and the ACT in the Midwest — that was regional habit, not policy, and it no longer reflects how admissions work.
So the choice is purely about which test lets you demonstrate your ability best. That is a question about you, not about the tests' reputations.
The science section is the biggest structural difference
The ACT has a dedicated science-reasoning section. Importantly, it is not a science-knowledge test — it is a data-interpretation test wearing a lab coat. You read graphs, tables and experimental summaries, and answer questions about them under significant time pressure.
Students who read charts quickly often love it; students who freeze at dense data often find it the hardest section of either test. If you are unsure, that section alone may decide your choice.
Timing: the ACT is faster
The ACT gives you noticeably less time per question across most sections. It rewards students who read quickly and commit to answers with confidence. The SAT gives more breathing room per question but asks you to reason more carefully from evidence within the passage.
This is the single most useful self-diagnosis: do you run out of time, or do you make careless errors when rushed? If speed is your weakness, the SAT's pacing may suit you better.
Maths content and calculators
ACT maths covers a slightly broader range, including some trigonometry, and permits a calculator throughout. The digital SAT allows a built-in calculator across its maths module too, and leans a little more on algebra and data analysis.
Neither is dramatically harder. The practical difference is again pace — the ACT gives you around a minute per maths question, which is unforgiving if you work methodically.
Scoring
The ACT is scored out of 36 (a composite of four sections), the SAT out of 1600. Colleges publish score ranges for both and use official concordance tables to compare them, so a strong score on either is read the same way.
How to actually decide
Sit one full, timed, official practice test of each — ideally on separate days, in the morning, without interruptions. Compare not just the scores but the experience: where did you run out of time, what drained you, which felt survivable?
Then commit to one and prepare properly for it. Splitting preparation between both is the most common self-inflicted wound in US test prep, and it produces two average scores instead of one good one.
Science, pace and the practical differences
The ACT includes a science section, which is really a data-interpretation test rather than a knowledge test — you read graphs and experiments and draw conclusions. Students who read charts quickly often find it their strongest section; students who panic at unfamiliar diagrams may prefer the SAT.
Pacing differs too: the ACT gives you less time per question, so it rewards speed and decisiveness. The SAT allows a little more time to reason, which suits students who prefer to think carefully.
Do universities prefer one?
No. Every US university that requires a test accepts both, and none regards one as superior. Any advice you hear that a particular test 'looks better' is a myth — admissions offices convert scores and treat them equivalently.
So the choice is purely about which format lets you show your ability best. Take one full practice test of each, compare percentile outcomes, and commit to the stronger one rather than splitting your preparation.

Frequently asked questions
Is the ACT easier than the SAT?+
Neither is easier overall — they are hard in different ways. The ACT is faster and includes science reasoning; the SAT gives more time per question but demands careful evidence-based reasoning. Fit matters more than difficulty.
Do I need science knowledge for the ACT science section?+
Barely. It tests your ability to read graphs, tables and experiment descriptions rather than recall of biology or chemistry facts. Some background helps you read faster, but data-interpretation skill is what is actually scored.
Can I submit both scores?+
You can, and colleges will typically consider your best. In practice, though, preparing well for one usually beats preparing adequately for two.
How many times should I take the test?+
Two or three sittings is common, with preparation between them. Beyond that, score gains usually flatten and your time is better spent on the rest of the application.
Are tests still required?+
Policies vary and have changed a great deal in recent years — some universities are test-optional, others have reinstated requirements. Check each university's current policy directly, since this is one of the fastest-moving parts of US admissions.
Can I take both the SAT and the ACT?+
You can, and some students do, but it usually splits preparation and lowers both scores. It is almost always better to identify your stronger test early with practice tests and put all your effort into that one.
