<p>I don’t believe so. I would recommend trying to get a good SAT score as well, just to show how smart you are even more, however, I don’t think you HAVE to.</p>
<p>@jsun365, MIT only requires either SAT or ACT (so do most other schools), along with a math and science subject test. Don’t worry about the SAT I.</p>
<p>You have three classes of colleges: (a) those that readily accept either SAT or ACT with no preference; (b) those that state a preference for one test over the other but still accept either; and (c) those that don’t require any test. To the best of my knowledge today, all but one college fall within group a or c. The one that is in group b is Cal Poly San Luis Obispo which about five years ago went from having no preference to stating a preference for the ACT. </p>
<p>You do not need to take both. Many do mainly to see if they can score higher on one over the other.</p>
<p>With a 36 on your ACT, there will be no need to sit for an SAT test ever. You are wise to still try SATIIs. High SATIIs, even if not required, tend to support an otherwise strong application.</p>
