Actually, his parents did something smart.
They told him, you learn/get homework done, you can do whatever you want.
Some people just don't learn the way the rest of us do. So, now he has very focussed periods of learning followed by marathon jam sessions. So long as his parents are supporting him with the education, he's probably better off.
I remember how shitty school was for me, I didn't think the same conformed thoughts the rest of the school did.
