I get the impression that you and ska are very, very good teachers. Not to disrespect any of my professors, but a lot of times I ended up skipping lectures because I just wasn't getting anything out of them. Was I a model student who always reviewed material before lectures? No. But I definitely felt I got a lot more out of going directly to the source materials and working problems than I did watching a professor walk other students through problems.
