Differences Between ACT and SAT & What Do Top Universities Prefer?

One of the most common questions students ask when exploring the Differences Between ACT and SAT is whether colleges prefer one over the other. According to official sources, such as the College Board and ACT, Inc., no U.S. college gives preference to either test; they accept both equally for admissions.

If you’re applying to a university that does accept standardized test scores, you’ll likely see no stated preference for ACT over SAT or vice versa. That’s because these exams are designed to measure similar skills in different formats, and admissions teams are trained to evaluate both equally.

So, the decision is entirely in your hands. Select the test that best aligns with your academic strengths and test-taking style.

How to Decide?

Here’s a simple way to think about it:

• Choose ACT if you’re confident in Math and Science and can manage time well. The ACT includes a Science section and often requires faster problem-solving.
• Choose SAT if you’re more comfortable with Reading, Writing, and Basic Math. The digital SAT allows for a little more time per question and includes built-in tools, such as a calculator and formula sheet.

If you’re unsure which test to take, try a full-length practice test for both exams. This will help you understand which exam feels more natural.
