Virtually all colleges will accept either the SAT or the ACT to fulfill their testing requirements. Some of the most elite schools in the country, including Amherst College, Brown, Duke, Johns Hopkins, Pomona College, Tufts, University of Pennsylvania, Wesleyan and Vassar, will accept the ACT with Writing instead of the SAT and the SAT subject tests.
So which test should you take? As this helpful article explains: “The decision as to which test should more be a matter of personal preference. If you are good at taking high school classroom tests, then the ACT might be the better test for you. It is curriculum based; it attempts to measure your mastery of key high school skills. The SAT, on the other hand, measures reasoning and logic.”
