Is vocabulary your weak link but you’re a strong math and science student? That sounds like a recipe for a date with the ACT, not the SAT. Let’s discuss.
Before I’d advise you, I’d like to see your PSAT results and speak with you about test taking. But it’s important to remember that your choice of which college test you take is just that–your choice. It doesn’t usually matter to the school you’re applying to (you should double check on your favorite school.) In some cases you have fewer testing requirements with an ACT than an SAT. The notion that “all my friends are taking the other test” doesn’t really matter unless you let it make you crazy.
It’s probably true that when you look at the whole body of students who take the two tests the scores come out about the same ACT to SAT. But for any given student, one test is likely to be easier than the other because of how it’s made. So why make this harder than it needs to be. Discuss it with an expert: portlandtestprep@gmail.com
