Question: For the college I got accepted to and am going to, I put on the application that I was taking the ACT and SAT another time. Will this affect anything if I decide not to take the tests again? I already have a really good score.
No, as long as you took the test(s) that your college required and submitted your scores, then you don’t have to re-test, even if you thought you would do so at the time that you submitted your application. You don’t even have to notify your college that you are not re-testing.
