I'm confused. At the universities I attended, or later worked at, lectures were absolutely, definitely, optional. That's how it should be. Universities provide a framework for students to learn. The university then tests what the student has learned in order to give them a diploma. How the student learned that is surely not important.

(Things are of course different when there are practical considerations to the teaching, such as labwork, which of comes with a degree of associated testing anyway.)
