Indeed it is - he's chemistry-mad currently (half way through ALEKS chemistry, and to my astonishment just read Sam Kean's The Disappearing Spoon with great pleasure*) but he also enjoys physics. These are good ideas, but I don't think they make the problem go away - he'd still be doing things on his own, and would still either be unchallenged or have to deal with challenges without significant teacher input. Well, I suppose that's it: he has to learn to do that![/quote]

Could he participate in an online class? He would still get support, and it may not matter that he is significantly younger than other students. They might not even know.
