Well if I know what the class requires and I study the material a year ahead before I take the class then aren't I really just waisting time going to lectures/lab just to get the credit? At that point Universities should just offer tests for credit in every class so students can skip wasting time attending a pointless lecture since learning is no longer the goal here. i.e. if college is $6k a semester, then just to get tested should be like $3k and let more serious/prepared students to graduate faster. Because at the end of the day you're just paying for accreditation. Otherwise it's just a giant circle jerk (we all know that it is already though).
