We’ve been preparing students for college admissions tests since 2002, and we’ve found there’s only one surefire way to know which test is right for your child: take a practice test for each exam.

Frequently Asked Questions


Do all colleges accept both tests?

Yes. All U.S. colleges accept both tests, and colleges do not prefer the SAT® over the ACT® (or vice versa).

Do colleges prefer one test over the other?

No. All U.S. colleges that accept admission tests accept both the SAT® and ACT®. Choose the exam your student can score higher on.

Is it true that Ivy League schools prefer the SAT®?

No. That may have been true in the past, but today there’s no preference. All U.S. four-year colleges that require an admissions test accept both exams.

Which test is more popular?

In 2024, approximately 1.97 million students took the SAT® and 1.4 million took the ACT®. The SAT® has been slightly more popular nationwide in recent years, though regional preferences vary.

Is one test easier?

Not exactly—they’re just different. Both assess similar academic concepts, but the formats and pacing differ. Approximately 20% of students naturally perform better on one test. We recommend taking both (ideally before junior year) to see whether the SAT® or ACT® is the better fit.

Is the SAT® now digital?

Yes. The SAT® and PSAT® are fully digital and adaptive, delivered through College Board’s Bluebook app.

Are both paper and digital ACT® offered at all test centers?

No. Availability varies by test center and date. Some centers offer digital ACT, some paper, and some both. During ACT registration you’ll see which format is available for your chosen location and date.

Will a “test-optional” school still look at scores?

If you submit a strong score, it can help with admissions, scholarships, and placement—especially at competitive schools.

How do I compare SAT® and ACT® scores?

Your Revolution Prep Advisor will help you compare results. ACT® and College Board also publish concordance tables to translate SAT® and ACT® scores.

What does it mean that the SAT® is adaptive?

The digital SAT® adjusts to each student’s performance in real time. After the first module, the difficulty of the second module changes based on how the student did. This keeps the test shorter while still accurately measuring ability.

What do you mean by the SAT® is more established or stable?

The SAT® has used the current digital format since early 2023 and is now the worldwide standard. Its question types, scoring, and interface have been used by millions of students, so results and expectations are consistent. The enhanced ACT® format is newer, with some variation in delivery and interpretation.

What’s the fastest way to decide between tests?

Take one practice SAT® and one practice ACT®, then do a 30-minute advisor review. Most families know the winner the same day.
