Natural Sciences study resources enough?

[testtaker]

Hi,

I used speedyprep (instacert didn't have the natural sciences test) and 4th edition of the below book, and felt very unprepared during the test, but I was surprised to pass with a 60.

I then found out that there was a newer version of the book - argh! (see below), and got it to prepare for Social Sciences and History CLEP. I then glanced through the updated questions for Natural Sciences and they were much more like the test, right on the money, I would have done much better on the test.

BTW... I used these books also for Social Sciences and History and passed no problem. It's a great resource (and cheap). I would just study this book and the CLEP Official Study Guide 2009 (also cheap) for Natural Sciences and take the test.
