Saw this by chance on twitter:

For what it's worth, I think he is right. You can learn a tremendous amount by reading and watching talks on the Web.

Those are excellent, I love how approaches everything in terms of the normal person who might find some concepts tricky and need a closer explanation. I've gone to lectures then watched one of these on the same content and he really explains it so much better.

The thing lecturers tend to do is assume everyone in the class has been through the same set of classes before the current one and assume many things should be completely obvious and not need explanation, when often they do.
