<p>I know that, generally, Princeton's Review and Barron's are highly spoken of when it comes to reviewing information for AP tests, but I'm also asking for books that'll prepare me for the course itself, and can be used as supplements to the textbooks.</p>
<p>Specially, I'm looking for prep and review books for the following:</p>
<p>AP Biology
AP Calc AB
AP European History</p>
<p>I'd like to hear about personal experiences with any recommended books, but I'll appreciate any suggestions!</p>
