<p>I need to study! I took a sample test that's in Barron's and got 620 - 650 range. I have to pull it up! I don't know if I should take it in May? I made several stupid mistakes. I think if I practice I may be able to pull it up. </p>
<p>Please tell me which books are good for prep. Thanks.</p>
<p>I think is barrons is already good enough, and their practice test are usually a bit harder and weird with answers. The best way to prep is to probably read everything in barrons and then review on sparknotes, and if your in Ap chem, it would be best if you review with the textbook, so you will be studying for both the sat chem and ap exam at the same time.</p>
