Both tests are equally accepted for college admission and either can be an excellent option. So which assessment a student should take — the SAT or the ACT — can be based largely on which test most leans-into your strengths. Below is a chart that compares the basic content, timing, and structure of the SAT and ACT to help better inform your decision. But perhaps the best way to determine the “right” test for you is to take a diagnostic assessment. These are often offered free-of-charge by test-prep companies; search for reputable options near you or online.

From there, preparation, practice tests, and studying or being tutored are the keys to testing success.
