Also, the SAT and ACT are a bit different, for example, the ACT has a science component and the SAT does not, so depending on your strengths you may score better on one than the other. By taking both you will have the opportunity to excel in the areas you’re strongest in, which should help you with getting accepted into more schools and scholarships as the other answer said. Definitely take advantage of test prep programs; knowing what kind of questions to expect is very important to your ability to do well. Good luck! You can do this!

There are also a lot of prep course out there so you don't need to worry much of finding a way to prep. One thing you need to do is get registered for the test slot early so you find the one that is best for you. They go pretty fast.
