Maybe I'm reading this wrong but my understanding is they aren't being GRADED on anything outside of the classroom. You shouldn't be graded on getting your homework done. That doesn't prove you understand the concept, it proves that you can finish homework (or in many cases, copy off someone else).
I like this idea, giving marks for getting homework done is ridiculous. For those of you who say "what are these kids going to do when they get to university". Simply the same thing they do now. Spend time on things that they need work on and spend less time on things they already understand.
Studying smart is a far better skill to learn then studying hard, these kids are learning to prioritize early in life, which I think is great.
