<p>Barron's biology SAT II is an absolute disaster. Stay far, far away; it's not well organized at all and has a poor grasp of what material you actually need for the exam. That piece of garbage has a whole damn chapter devoted to drugs (important vocab words include "pusher" and "crack"). Amount of the SAT II devoted to illegal drugs? Zero. I also remember finding several non-trivial factual errors in the Barron's book.</p>
<p>Princeton Review is the best for the Bio SAT II, E or M. I studied from that having never taken a biology class, and got a 780.</p>
