Need help choosing tests!

[mphelps75]

I am a newbie here and have been lurking for over a week and this is my first posting. I am in need of 9 credits by the end of the month and I am trying to psych myself up to take these tests but I am just to scared to fail which is so unlike me. I am so intimidated that everytime I go to study I just can't get a flow which is part of the reason I joined. I have watched all of the positive reinforcement everyone has given each other and I figure this is the place I need to be if I have any hope of pulling this thing off. So far these are the tests I think I want to attempt...anyone have any feedback on how easy or hard they are? Any help is appreciated...I found the test specific forums and the tests below might be my best bet??
Thanks

Here's to your Health
Ethics in America-(although so far study has been SOOO boring)
dsst Law Enforcement
DSST Principles of Supervision

any others?? I am open for ideas I have a very short window to study!
