Biology super cram - is this possible?

[Back2School]

Ok I'm in a bit of a need to super cram biology. I'm graduating from Walden University and have only one math/science class course requirement remaining. Since I have already transfered a calculus class I must take a science. They have approved that either Natural Science or Biology CLEP will be acceptable. Now the rub. For me to graduate plus get into the MBA program for this term I must take the test before the end of this month - Oct 31st. Because it is my very last class and I have a 4.0 GPA they are going to accept a faxed copy and allow me to be accepted into the MBA program contigent upon the final transfer. Basically it will put me 3 months ahead on my MBA if I can pass this test by Oct 31st. It will also likely affect my final graduation day by at least 6 weeks.

I didn't find this all out until this past Wednesday and of course I started studying immediately. But I can see already this is going to be very, very tough to learn all this by Oct 31st. I've downloaded the Cliff notes, have the official CLEP study guide, Instant Cert, Petersons tests (haven't taken any yet), and of course the online biology book. So far I have probably 10 hours studying in and will of course study all weekend. My main problem is that I'm 39 and had my biology class in highshool 25 years ago. I remember nothing at all.

I'm going to go ahead and give it a shot. I will study all day today (Haloween party tonight that my wife is very excited about so I must go), and all day and night tomorrow. I work during the week of course so I'm expecting evening study during the week. I'm figuring I should get about 25-30 hours of "quality" study time. If I fail then I can study harder and take Natural Science in a few weeks or a month or whatever. I was curious if anyone else out there was able to cram biology into a few days study or if I'm just going to have an excercise in frustration. Any tips or suggestions are much appreciated.
