The fact that many universities have tenured masters of their domain still having to, even with as many grad students as can fill a lecture hall, oversee 100 level courses that would fit in better at middle school than university is ridiculous.
Good professors are an extremely expensive thing to have, and students of merit deserve time with such masters that maximizes knowledge transfer. That almost always means not having regimented, graded curriculum taught by lecture from one singular book, but that is how almost all university courses operate.
Any time a professor repeats themself or is forced to do something mechanical or routine is a failure of the system to take advantage of their ability.
