"barnes and noble university" -- anyone done this?

I stumbled across some online courses at the Barnes and Noble website. There were actually quite a few offered, and they looked fairly interesting.

Before I take them, does anyone here have any experience with these particular online courses? Are they any good? Since they’re free, can I expect to get what I pay for in that regard? I’ll probably end up taking a couple anyway just for the hell of it, but I’d like to know what kind of quality I can expect.

Thanks!
