If the class is hard, then the schedule serves an important purpose, which is to keep a group of students together at about the same point in the curriculum. That way, if some of them get stuck, there will be other people working on the same material at the same time who can help them get unstuck. I have learned (and tried and failed at learning) some difficult material through pure self-study in the past, and when you get stuck, you can stay stuck for a long time.
