<p>Over the summer I bought a prep book from cliffsnotes and its helped me with my ap bio class. I know that there is a revised exam this year, but is it possible to use the book I already have? I'm trying to save money. However, if the new exam is really different, then I don't mind. If so, whats a good brand for the 2013 ap bio exam?</p>
<p>Hey purpledino. The new cliff noted isn’t out yet, but most of the other books haven’t really updated themselves all too well to the new course. However, a FREE AND ACCURATE “review guide” would be the college board PDF which is the new curriculum overview and is very very detailed.
