<p>What are the best ways of studying for these two classes? And what are the best review books?</p>
<p>cliffs ap bio.</p>
<p>hmm im taking biology this year, i got barrons review guide and am using campbells 7th edition. world history i used my schools ap world text book (forgot what its called) and no supplemental review guide. we didn't even finish the last 8 or so chapters. i tried reviewing thru the massive book but it was pretty impossible due to its size. i gave up studying, relaxed and walked out with a 5 somehow. but yea, a review book would have definitely have made my life easier.</p>
<p>I recommend Cliff Notes for AP Bio and Princeton Review for AP World History.</p>
