<p>So, right now, I have a 690 on math (in practice tests and on PSAT i got ~750). My main problem is making tiny, stupid mistakes in the harder problems. I'm currently going through the Princeton Review book, and while it has some good hard problems, it just isn't geared towards being predominantly about the harder questions (understandably).</p>
<p>So which books are good for getting that 800?</p>
