What is the difference between the SAT and ACT®?
The ACT tests a broader range of material than the SAT Reasoning Test (in some ways it is similar to the SAT Subject Tests) and some students perform better on it than they do on the SAT. Almost all colleges will accept either SAT or ACT scores (although some states prefer one over the other), so taking the ACT in addition to the SAT can give you another shot at improving your odds. If you do poorly on the ACT you can simply choose not to report your score. (Make sure that you don’t sign up to send your score to any college automatically).
