I used cracking the CLEP for Englsih Comp. I also took the Excelsior College Writing and used the MyAccess writing tool that's included with purchase of the exam. If you have plans to move to Excelsior keep in mind that the CLEP will not count towards their written english requirements. The exam will only count for 3 humanities credits (assuming that the exam doesn't overlap with other english courses beyond the first 3 credits).
