I'm also taking the test Saturday. I'm pretty much in the same situation as you, with the only difference being that I've taken AP Bio. To review, I've been using sparknotes, which has review material and 3 practice tests with scoring and analysis (you do need to create and account). I've also been using info from the link below: http://www.xtremepapers.com/papers/S...%20Biology.pdf
This is pretty much a review booklet online. It has review material, along with 3 practice tests. There is no scoring guide to the tests, but Sparknotes has one, so you should be good. I don't have a review book tailored to the test, but a friend of mine who took the test and got above a 700 (she wouldn't give me precise info) used the Barron test prep book. I'm using Cliff's AP Bio review book from last year to prep, and that book was a saving grace for me last year for the exam. I hope this helps; good luck!
