Me and my kids tended to ace tests without studying, often with the barest understanding of the material (that vanished soon after). I'd guess his solution might be to have a complex representative problem to solve as proof of knowledge. Have it ready at the beginning of the course and as soon as kids can solve it, they're done. Unfortunately, this doesn't line up with predetermined schedules which tend to dominate every mm of schooling.
