That's true. The system has settled - after a few millennia of experience - on an all-students-gotta-do-their-homework model. What scalable, affordable system would have the best total outome, given real student populations? That's the problem for the public system to address. Note that this is not the same question as "what's best for betterunix".

I have a lot of sympathy for you, as a student who did as little homework as I could get away with or a little less. Lucky for me that exams were more important back then. I might have more trouble nowadays.
