<p>I've heard mainly PR. I am also going to be taking AP bio this year if that makes any difference. So, what do you guys think is the best and why?</p>
<p>From my experience Kaplan’s was the most challenging with Barron’s being the easiest and Princeton Review’s in between.</p>
<p>Anyone else?</p>
<p>I found Barron’s too hard. I read about half and it really does overprepare you, something that really didn’t help me since I felt as if I had to know everything.</p>
<p>My favorite was PR.</p>
<p>I think Barron’s and Cliffnotes will prepare you well enough for the exam</p>
<p>I used CliffsAP. Just CliffsAP. I think I got close to an 800…</p>
<p>I didn’t read through Barrons or PR and only used them for practice tests so I can’t really tell you how their reviews are. The Kaplan version has a lot of information (though I assume this is true for most review books) and I looked over it but didn’t read the whole book. Kaplan’s practice tests were the hardest, I actually thought some of the Kaplan questions were harder than the SAT 2 Bio questions. I think if possible you should use the practice tests from both PR and Kaplan (PR had a question that was exactly on the test if i a remember correctly) and review from whichever you prefer.</p>
<p>The combo of Barron’s and PR is good for review. Barron’s has some great charts that make it much easier to memorize. A couple of questions seem to always be similar to Princeton Review questions. So both are good. I don’t think Barron’s material is that much harder than the actual test. I mean, it might be overkill, but you never know what info is going to be on the test.</p>
