<p>I already have Cliffs AP book. Should I get the Kaplan book?</p>
<p>i recommend sparknotes, maybe princeton</p>
<p>sparknotes for the win</p>
<p>i used sparknotes, kaplan, and pr.</p>
<p>well i know sparknotes lacks some things...but i think they left it out cuz they know it doesnt show up too often.</p>
<p>ex: sparknotes lacks explanation on retroviruses / auxotrophs</p>
<p>on the nov. bio test, retroviruses happened to come up. it doesnt come up too often.</p>
