CLEP Biology and Chem, advice desperately needed

[cookderosa]

Hello,
SCENARIO: Any advice is very highly appreciated as I am in a really rough situation. I was screwed over by an adviser and now have 7 days to pass either the chemistry or biology CLEP or I will have to go into some harsh debt to take a course. I can dedicate all day, everyday to studying.

BACKGROUND: I got perfect scores on my ACT without studying, science/mathlete from high school, in my final year of undergrad math/statistics with a 4.0, I learn things quick but haven't touched either subject for 5 years.

EXAM: Which exam should I take? A friend who took both suggested I take chem because I don't need to learn any math and can figure out a lot of it by the math I know. But, I haven't touched either subject for 5 years and all the resources say biology is the easier exam by far.

STUDYING: I have done research on studying for biology and it seems using a website (InstantCert) and textbook combined are best. And for textbook, should I use the official CLEP REA review book (link 1 below) or the Cliff AP book (link 2)?
I read somewhere that there are lab questions on the biology one that are only covered in the AP book, any truth to that from your experience? Also, I know khanacademy and hippocampus vids are helpful but those are a lot of videos. Which sets specifically on hippocampus do I need to look at?

DOABLE? Is it possible, considering my background, to pass this a week from now, given that I study every day for lengthy periods of time? Should I take notes and read and re-read the materials or can I just skim it over? Thank you very much in advance for any help.

PS: Biology book has good rating on amazon but I also stumbled across this, which made me wonder:
BARNES & NOBLE | CLEP Biology with TestWare by Laurie Ann Callihan, Research & Education Association | Paperback

I'm going to suggest chem for the same reason as your friend. Chemistry math eats students. Chemistry has its own rounding, uses significant digits, and is in metric with gads of exponents- positive and negative. That's before you talk about "chemistry" stuff. For that reason alone, I think you'd be up to snuff on all chem math within one afternoon. There will be a lot of math on the exam, especially weights and conversion. Your intuition will help you do very very well. Do chem, hands down. *there isn't any math in bio

Get your library's copy of Idiot's guide to chemistry or chemistry for dummies and the CLEP official guide- any within the past 5 years is fine. If your library has an AP Chem or CLEP chem, get that too. Read through it, use Khan, and you'll be golden.
