What if we moved to pass/fail grading? Every assignment and test is just marked pass or fail. Realistically tempered by what percentage you're allowed to fail for the class, e.g. 40% for university calculus - no different than grading on a curve today. Fail any N assignments/tests and fail the course. Maybe some are weighted to count extra, e.g. Final project, midterm, final exam. This is really not much different than the current system, but if you stop caring about the difference between C and A, students can either slack off or focus more on learning (if the subject is interesting). Nobody cares about your grades after your first job anyway. I had nearly a perfect GPA in college, and it was a terrible waste of time in hindsight. If I'd spent more time socializing maybe I would have made some lifelong contacts that would have benefited my career or become co-founders with me. I've always thought to tell my hypothetical kids to not sweat the grades and remember that the benefit of university is really the friends (and sometimes life partner) who you meet there. It's total shit when it comes to learning stuff. A self motivated person can learn more in a year than a 4 year degree. Somewhat depends on the subject though - I wouldn't want a self taught doctor who didn't do the practical parts of the education.
