I experienced this method in a public high school I went to. It was actually an awesome model and schooldays were 4 hours. The unfortunate thing about high school is the actual materials are really low quality.

Looking back, only math is a useful class in high school (of which I only liked Geometry at the time). The other classes are too low res to be deeply engaging if you're really curious.

Traditional schooling also has a terrible model of punishing curiosity in that if you demonstrate a passion for the material it likely just ends up with more work/homework (AP classes, special credit) instead of acceleration to the next tier of education on that topic. The grade school education system does nothing to reward academic excellence, literally nothing. If you get an A then thats it. You're still locked in with everyone else, so whats the point?
