<p>i know that the Cliffs notes is said to be the best one and i have that one i want to buy another one just incase something is missed in cliffs. I am self studying, and i need a 5 on this exam. WHat is the second best Prep book for the AP Biology exam.</p>
<p>Cliffs is definitely the best.</p>
<p>I’ve read parts of Princeton Review, and I didn’t think it was very good.</p>
<p>I haven’t read the Barron’s AP Bio review, but the Barron’s AP Chem was VERY rigorous, so you might want to try that one.</p>
<p>thanks allot for your reply man i’ll check out the barrons thanks again</p>
