He's young, but if you can afford the home study course, buy it. I'm an ex-teacher & it's a terrific course.
If you or his father could have the interest to work w/ him, this would help his assimilation of it. It's just a technique. I also think that kids like him who have the interest will do MUCH better than many adults who have all kinds of hang-ups w/ regard to their personal success.
Make sure he does it in layers & has fun. But, please be interested & listen w/ him when he listens to the tapes to help answer any questions he may have.
