Absolutely, yes. A little while ago, only Midwestern colleges used the ACT for admissions, and the more “established” schools only accepted the SAT. Now, colleges realize that both tests are equally challenging (though in different ways) and accept the ACT as a fully legitimate entrance exam. In fact, in some cases, the most competitive schools have lower average ACT scores than SAT scores, and so prefer high ACT scores over equally high SAT scores. The bottom line: take the test that’s best for you. To make that decision, read our free guide to the SAT vs. the ACT here, which will show you how to compare scores and pick the best test for you.
