Time to get a degree using CLEPs

[ChaserRu]

I have 24 traditional credits right now and will have 30 by the end of this semester(December). I am going to begin taking CLEP tests as tests are my strong point in classes. My last class(night class), I only went to about 20% of my classes and read the chapters for about 2 hrs before the tests and got 2 Bs and 1 C on the test.

I am hoping to take one every Friday, but I'm wondering if that seems a bit too much ?

I am trying to sign up for IC online but it is having an issue with my CC and i'm not sure why. I figure that'd give me a ballpark on how long studying would take as I read 90-95% is required to really do well on a test.

Thanks
Chase
