<p>They're not really for SAT prep. I just got chance to look at two of them and they're soooo good! They certainly will help me to do better in math next time I take the SAT.</p>
<p>The AOPS books are really good for competitive math prep. They really help on stuff like the AMC and AIME.</p>
<p>I have used almost all of them and they are absolutely wonderful! They help on everything and not only do you learn stuff but you understand it which makes remembering wayyyyyy easier. Imagine not looking at all the math formula’s for hours the night before the test to memorize them??</p>
