<p>So I'm using Campbell's Biology Concepts and Connections Sixth Ed. and I'm looking for a secondary textbook to use.</p>
<p>Also any recommendations on prep books in addition to Princeton Review will be appreciated!</p>
<p>I'm really freaking out about AP Bio b/c I need at least a 4 and I've been doing pretty badly in the course.</p>
<p>campbell’s book is probably the best. What I would recommend instead is getting a review guide for the exam. That guide will tell you exactly what need to know for the exam.</p>
<p>Remember, the textbook is designed to teach biology at a college level.
While the prep guide is designed to help you pass the AP bio exam.</p>
<p>There is a difference.</p>
