Both tests are accepted by every major US college — but they have meaningfully different formats, and one may play to your strengths far better than the other. Here is everything you need to know to make the right call.

What do these scores mean in practice? Here are score ranges for different tiers of selectivity.
| Selectivity tier | SAT range (middle 50%) | ACT range (middle 50%) |
|---|---|---|
| Most selective (top 20) | 1510–1580 | 34–36 |
| Highly selective (top 50) | 1400–1520 | 31–34 |
| Selective (top 100) | 1280–1430 | 28–33 |
| Competitive | 1150–1320 | 24–29 |
| Less selective | 1000–1200 | 20–26 |
The vast majority of four-year colleges in the United States accept both the SAT and ACT equally. Admissions officers do not prefer one over the other. A strong score on either test carries the same weight. The decision of which test to take should be based entirely on which format plays to your strengths — not on any perceived institutional preference.
Neither test is objectively easier — the answer depends on your strengths. Students who excel at math and prefer fewer questions with more time per question often do better on the SAT. Students who read quickly, think well under time pressure, and are comfortable with a Science Reasoning section often score higher on the ACT. The best way to find out is to take a full practice test for both and compare your scaled scores.
Superscoring means a college takes your best section scores across multiple test sittings and combines them into a new composite. For example, if you scored 720 Math / 680 RW on one SAT and 680 Math / 750 RW on another, your superscore would be 1470 (750+720). Most selective colleges superscore both SAT and ACT. Always check the specific policy for each school you are applying to.
No — the ACT Science section is primarily a data analysis and reasoning test, not a science knowledge test. It presents graphs, tables, charts, and experimental results, and asks you to interpret them. Strong readers who can quickly extract information from data do well on this section even without deep science knowledge. The main challenge is time — 35 questions in 35 minutes is fast.
The digital SAT (introduced 2024) is widely considered more approachable than the old paper format. It is significantly shorter (2h14m vs 3h+), uses an adaptive format that tailors difficulty to your performance, allows Desmos calculator throughout Math, and has shorter reading passages with one question each. Most students who have taken both report finding the digital format less exhausting.
Both are accepted equally at all Ivy League schools, MIT, Stanford, and every other highly selective university. Harvard, Yale, Princeton, Columbia, and others publish explicit statements that neither test is preferred. Your choice should be based entirely on which test produces a stronger score for you. Take a practice exam for each and compare.
Most college counselors recommend taking your chosen test 2–3 times. The first sitting gives you real test-day experience. Many students improve meaningfully on a second attempt after targeted preparation. A third attempt makes sense if there is a specific score threshold you need to reach. Taking the test more than 3–4 times rarely produces significant improvement and may look unfavorable to some admissions committees.
Yes — both College Board (SAT) and ACT, Inc. offer fee waivers for eligible students. SAT fee waivers cover the test fee and provide four free score sends. ACT fee waivers cover the registration fee. Eligibility is typically based on income (e.g., qualifying for free/reduced lunch, or family income below a threshold). Students should speak with their high school counselor to obtain a fee waiver.
