Hi jcanion,
I took both the Biology and Natural Sciences CLEPs (one in May, and one in early June). I am not a science major, and have not taken a life science-related course since high school, so I was apprehensive about those exams myself. However, I studied for no more than a couple of weeks for each exam, and scored a 58 on each one. Yippee!!
Thanks to all of the helpful advice I read on this discussion board (thanks, everyone!
), I studied for and took the Biology CLEP first. I agree, it is better to take that one first. I used IC and found it very helpful, but I had difficulty getting through the huge volume of flashcards. Come to think of it, I am not sure if I actually got through all of them.
Except for the monthly cost for IC, all the material I used for these tests were free Web resources. This may sound a bit silly to some, but the most helpful resources for me when it comes to studying for something like science, are science sites that are geared toward kids. They explain the same concepts we need to know, but they do it succinctly and in easy to understand terms.
Both the Biology and Natural Sciences CLEPs focus a lot on cell biology, and it is important to know the names and functions of the different organelles. The Web site that helped me most of all with this, hands down, was Rader's Biology4Kids (
http://www.biology4kids.com/index.html ). That site sufficiently explains what you need to know about the various cell organelles for the CLEP exam. It was also sufficient when it came to plant biology and photosynthesis. Pay special attention to the functions of xylem and phloem.
There is a little bit about the plant and animal kingdoms on the biology exam (I cannot remember if it is on the NS exam or not), and the Kidzone Web site (
http://www.kidzone.ws/animals/scientific.htm ) helped me with that.
Although not a kids' site, the NOVA Online flash demonstration (
http://www.pbs.org/wgbh/nova/miracle/divide.html# ) helped me most when it came to understanding the process and differences between mitosis and meiosis.
The following sites were also very helpful to me:
A demonstration of membrane transport (both passive and active transport)

To get a better grasp of genetics, the Fly Lab was very helpful to me

I hope this helps; and, best of luck with your tests!
