<p>What should I do to prep? Any good books or online resources? I'm currently a junior in ap calc</p>
<p>It’s actually more advantageous to take it right after precalc. However, you’ll probably still do fine. Barron’s book is the best; way harder than the real test, so it’ll prepare you well.</p>
<p>By the way, you’ll have more luck getting responses if you post in the SAT subject test subforum :)</p>
<p>Good luck!</p>
<p>if you’re pretty good at math, I’d recommend just doing a couple official practice tests. That’s all I did, and scored an 800 pretty easily. If you are only decent in math, then I’d recommend getting a prep book (I heard Dr. Chungs and Barrons are really good because they are much harder than the actual test, and overprepares you for it)</p>
