best ap prep books for bio, us history, eng lang?

<p>the title says it all. I'm looking for at least 1-2 supplementary books for each subject...thanks so much!</p>

<p>get cliffnotes +barrons for biology ..barrons is a bit overprep but its pretty good....</p>

<p>cliffs for bio, and amsco or rea for USH</p>

<p>bio-cliffs. if you are taking the sat2 try kaplan.
ush- amsco.
lang- cliffs, and you really need to practice essays.</p>

<p>bio- cliffs
ush- amsco (i really cant find any cheap ones anywhere!) or REA
english- princeton just cuz of the new synthesis section and practice essays</p>

<p>for amsco, I have the "Book Review Text" amsco version, is that fine.</p>

<p>It's US History Review Text, I am wondering if that is the right amsco book.</p>
