Passing a CLEP does seem to get you hooked. I took Intro to Sociology today, but it is my last one. For Now
I agree a pass is a pass and the first one is the hardest, but if I was you I would try to study a little more for the next one, not passing especially when it is only by a point or two is a real bummer.
If you need any resources for A & I lit PM me your e-mail I will send you lots.
