Not that serious a teacher, which is okay, because all of us get tired of those professors with high standards. He basically reads off lecture notes, is super flexible and available if you need his help, and gives out easy assignments. But don't get lulled into a false sense of security in his class. I went in thinking this class was a piece of cake (and it is, mostly) but then I ended up with a terrible grade on the midterm. You still have to be alert and study. Don't let his niceness catch you off guard. It's still school!
