Colleges generally accept both tests, so the choice comes down to which one suits you. Both have changed recently. These details come from 2026 test-prep sources, so confirm them with ACT and College Board before you register.

Which one fits you
- You work carefully and like time to think: lean SAT.
- You work quickly and know your geometry formulas: lean ACT.
- You rely on a graphing calculator: the SAT's built-in Desmos helps.
The best way to decide
Take one full practice test of each, under real timing, and compare your scores with a concordance table. If one is clearly higher, study for that one. If they're close, choose the format you liked more. Then commit, since preparing for both splits your time.
Watch out for this
Choosing a test because friends are taking it.
Your own practice scores are better evidence. Each test takes only a few hours to try.
