DD had similar scores when she took the SAT about a yea ago, just before turning 13.

My advice is contrary to many as I am not a big fan of acceleration. It might be worth one more search if you can find a really good school system where your son fits in.

We happen to be in one such public school system, and while DD is near the top of her class, there are a few that are even stronger. She has the confidence of doing well in school, and the benefit of fitting in with her age peers.
