Okay then. I just dropped out of my second Coursera "introduction to" class. Before I did I went to the user forums and found an ongoing discussion about the frustration level in the class. Several people with post grad degrees in math, chem, and the like were all stumped.

I guess the term "introductory level" doesn't mean what it did when I was in college. Thanks Coursera, now I feel really dumb. I guess I'll just stay  with Kahn and the occasional Stanford class.
