Bio Clep Retake - Advice please

[financemajor]

Hi,
I'm trying to take the biology clep and could use any advice. I failed it the first time I took it a little over 6 months ago with a 49 (so close...) and I really need to take this clep to finish my general ed requirements at college. The first time I took it I used REA Clep prep book and when I got to the exam I felt like most of the questions on there were not covered in the book. So I figured I'll try to do it differently this time so I just registered for InstantCert and got the CliffsQuickReview Biology book which I plan on studying. As I said, I really can't afford to fail and I've got a bit less than a month to do this since I'm trying to get it done before next semester starts... So any advice???
Thanks!
ps- I've taken and passed several other cleps before in the past- management, marketing, sociology, humanities, and college algebra. But bio just seems to be the one clep staring me in the face as the biggest challenge...

I took this exam without ever having any previous knowledge of Biology a few years ago and passed with my highest score. I used the AP Biology book and it well covered most of the test.

Use Khan Academy videos and the exam feedback...good luck!
