There's a stage of puberty boys go through where it would work better to give them a whole schedule of Shop Class/Gym/Work-study, or similar for that year. They're re-learning how to control and move their growth spurt body and re-learning how to think with the suddenly increased Testosterone level.

Tracking folks earlier would also probably help. A lot of my peers growing up worked 4 hours of their school day their senior year, those guys all own homes way before my college bound peers did.
