DSST Physical Geology and Human/Cultural Geography

[tcc]

After having thought I'd finished with all of my tests, I was told by Excelsior they had made a mistake and that I had to come up with three science credits to meet my distribution requirement. So I'm studying for physical geology, and here are the study materials I've located: Cliffs Quick Reviews/Physical Geology (buy it and download it from the CliffsQuickReview website), and from my local library: Earth Science, Demystified by Linda Williams, and Earth's Dynamic Systems by Kenneth Hamblin (which is one of the recommended books by DSST). I bought and downloaded the SparkChart on geology and earth science from sparknotes.com, and have bought, but haven't yet used Jack Rudman's study guide for this exam. It's mainly test questions, and the part that provides information on physical geology doesn't look very good. However, I haven't taken the test yet, so I don't really know that. The Cliffs Quick Review is packed with information, and I'm betting it could be used without any other study guides.....but why do that when books are available at the library for free?
