I studied for a week and a half for the following DANTES CLEP and passed all three. I took Drug and Alcohol Abuse and Fundamental of Counseling on the same day and Ethics in America the next day and passed all three.

I only used InstantCert as a study guide. My scores are as follows:

Drug and Alcohol Abuse 59
Fundamental of Counseling 54
Ethics in America 61

I am only 5 classes away from my degree in Business Information Systems and plan on CLEPing 4 of them. Next up is Humanities and Analyzing and Interpreting Literature.
