One of the things to that I found confusing with the coursera classes was that each one seems to have its own set of rules for dealing with homework assignments, late homework, and partial credit. At one point I was signed up for two classes at the same time and I assumed they had the same policy for when homework was due. It wasn't a big deal but there were several times I would have a free hour or so and it was a task to figure out the best way to use that time. I think it is a positive thing that the courses are trying out a lot of different approaches to see what works best but this reminded me of the parts of academia that I didn't really care for.
