Not that much. I remember the importance of sleep when you're learning (well explained in the course), and also spaced repetition and the importance of recalling the material on your own. I also remember that the instructors were very good - positive and enthusiastic, and that they explained the concepts very well. In general, it's hard to remember contents of courses I think. I often try to write a review of the course, either as a blog post, or on one of the review sites (Course Talk or Class Central). The act of deciding what was the most important parts, and expressing it in words go a long way towards remembering better.
