Ive read quite a few, so if you list some I might be able to give you a rec. I don't have any credits atm, so I am not quite sure if every course is up for sale or just a selection
It's a selection, but there are over 150 on sale.
I think I am mainly interested in the History courses, since the science stuff seems pretty basic given my background.
