Kaplan University is cheap compared to most universities out there. What is the big deal?
Often true, but so many of those for-profit "universities" are just diploma mills. A good test would be to call up your state university, and ask them if they accept Kaplan University credits. I'll bet they don't.
Another thing to consider, in general. When a for-profit tells you that they are "accredited", ask: accredited by whom?
I recall reading about once such institution that had accreditation...awarded to it by it's own in-house accreditation agency. Slick, eh?
