I know you'll hate me for this...but sat2/ap book help please

<p>I've searched a million times over, and I can't seem to find what is the best prep book for ap euro and the sat2 bio test? Would you agree ap bio, cliffs is the best, for the sat, the official guide, for math2c, barrons and for the act, princeton review or the official guide?</p>

<p>I used Cliffs for AP Bio, and I got a 3 (but I had it first semester, and only got through half the book), but a friend used PR's SAT II book for Bio and got a 720 and 5. Barrons is really tough for IIC, so be prepared to knock your head against the wall a few times. For AP Euro, I'm using PR, REA and Modern Euro History (Birdsall Viault). You are now my worst enemy. Bye</p>

<p>Cliff's and Barron's are considered the best for AP Biology, while Kaplan is at the top for SAT II Biology.</p>
