<p>How is PR in comparison to cliffs? My teacher recommends PR, but in my experience the PR books are a bit watered down. Also has anyone tried 5 Steps to a 5 for AP bio?</p>
<p>I used Kaplan and loved it, if that helps! (And got a 5, after getting a B- as a final grade in the course)</p>
<p>Cliff's is AMAZING.</p>
<p>Use that and Campbell's.</p>
<p>reading cliffs twice over got me a 5</p>
<p>tried cliffs for chemistry though and it sucked...definately use cliffs for bio though</p>
<p>get cliffs</p>
<p>all the ap bio students at my school have to get it and apparently it works wonders (although i won't know till next year)</p>
<p>Princeton Review does a better job at providing an overview and helping put the information in the right context, but Cliff's Notes are better for raw information. An amalgamation of the two books is a straight path to a 5.</p>
