We'll think about it but my husband thinks we should push him

because he won't study at all if he's done with his homework. Everyday we have to remind him to do his Kumon or practice piano. He complained they took too much of his time but if he has extra time he'll go to a friend's house playing games on the computer--I put a password on ours so he can't play it at home. That's why we have to make him study. But he doesn't appreciate it. Once in a while he seems to be mature but another minute he is a teenager again.
