<p>Out of these four books, which is the best?</p>
<p>You didn’t list it, but I’ve heard that Cliff’s AP Biology is extremely good.</p>
<p>My parents told me that they weren’t going to buy AP books. So I have to library borrow them. And that’s all they have ^</p>
<p>I’d try Barron’s.</p>
<p>If thats all they have, go with Barrons. Personally, I used Cliffs, but I hear Barrons is really good too</p>
<p>I have gone through Barron’s, PR, CliffsNotes. Personally, I’d say CliffsNotes is the easiest to follow (although the syllabus is covered with adequate depth) - But you would want to consider Barron’s ONLY for the practice tests. They’re a tad bit difficult but help you quite a bit. PR’s AP Biology is good, but not excellent like Cliffs & Barrons. </p>
<p>Also, do the tests of 5 steps - they are pretty accurate</p>
