ECE English Comp is 6 credits. Besides fulfilling the WER, it also gives you 3 lower-level Humanities credits. CLEP A&I Lit and CLEP Humanities are 6 Humanities credits each, but lower level, so it seems you'd end up with more lower-level credits than you need.

I guess I'm not quite clear on your needs. Are the 15 Humanites and SocSci/Hist credits in addition to the 5 lower level and 17 upper level General Ed credits? If so, are those 15 lower or upper level or a mix?

Rise and Fall of the Soviet Union and Civil War and Reconstruction are both DSSTs, and are three upper-level history credits each. I scored an A on Civil War and Reconstruction, but I didn't take R&F of the USSR -- it has a reputation of being tough. Research Methods in Psychology is an upper-level three-credit Social Sciences ECE that's quite passable (you should have a decent command of Statistics, though). Take a thorough look at the Student Guide and Assessment Catalog -- that's the official list of what exams cover what credits.
