What is the best prep book for the SAT II Chem?

<p>I really want to do well, but am not sure what prep book to use...</p>

<p>what do you guys suggest?
and if you have already taken the test, any tips?
what are some things we should know that some prep books may not necessarily cover?</p>

<p>Thanks in advance!</p>
