Has anyone found the free online petersen's practice exams beneficial?

[Almost_There]

I understand from the collective G2 that Peterson's is harder than the actual CLEP.

I am currently studying for Hum100 and Soc100 --- and after taking the Peterson's Intro to Soc pre-test (scored a 65%), I was shocked that it covers much more ground than IC study material did.

Also, Peterson's coverage seemed more in line with the percentage breakdown provided on the Collegeboard site for the Intro to Soc exam (copied below).

Thoughts and Comments --- I am planning on testing Soc before next Strayer semester starts (1/7/08)
