Astronomy....help???

[Aubs]

I'm working towards taking the DSST Astronomy test. The study guide is teeny weeny, no practice tests, and it's really freaking me out. I'm used to taking several different practice tests before I take the real one and now that I have none...it's scary. If someone could calm me down with details of the actual test, that would be wonderful.:confused:

Does anyone have some suggestions for outside sources that would make me feel a little more confident when I walk in to take the test?

I have books from the library. I also have my own account on flashcardexchange.com so I can make my own flashcards.

If anyone has any suggestions or hints, I would love to hear them!
