<p>I'm a sophmore in high school in NY and I have approx. a 1700 on the SAT. I took Kaplan and I'm starting Revolution Prep, are there any other good prep courses? I heard Princeton was pretty good?</p>
<p>You can significantly improve your scores self-studying, but the best course IMO is testmasters. (The one with the .com at the end). The online course and the in class courses are pretty helpful.</p>
