I have mixed feeling about this course. I find the subject - informal logic - fascinating. The pace of the course, however, is very slow. There is a LOT of repetition - mostly on one of the professor's part - and hours of video to watch each week. Plus, one of the professors developed smart exercises and quizzes - in the sense that the answers are fairly clear-cut and not really open for lots of discussion (this is, after all, a Philosophy class), but the other professor created exercises where he's clearly trying to trick us more than testing our understanding. It's frustrating as hell.
I would recommend that future version of this course are shortened. If you keep the contents but remove the repetition you can shave off at least 2-3 weeks of material - that's how slow the course is.
