Over-studying?

[Sammy]

I generally recommend instantcert to give a good accurate outline of the exams. So study instantcert well. I always recommend at least one additional study source. For clep, I recommend the CollegeBoard CLEP official Studya guide. Take the practice exam to evaluate where you are in your study process. For DSST, I recommend the fact sheets from thier web site which usually has a 10 question practice. Then I also highly recommend the Petersons practice exams.

Like I say, I always recommended one extra source besides instantcert but obviously it is not required unless you want to kick someones butt like I did with Snazzlefrag in statistics...but then again he kicked my tail in Socialogy with less study time and materials. So there is no absolute right answer. BTW, you usually end up with about the same exam results as you do with the practice exams.
