I understand your point of view: just watching the lectures offers an interesting high level overview.

However, the weekly quizzes offer a great learning experience. After watching the lectures for a week, keep taking the quiz over and over again until you really understand the material. Each time you take a quiz you get (mostly) different questions.

For some of the classes you also get a lot of additional material in the homework assignments.
