22B, it isn't that the college would reject him for lack of math, but a HS might not let him graduate (need to check local rules). Do you have a decent four year college near you? Near the MS and HS so it is easy for him to get back and forth? If he is in third grade now, is he in Geometry? I found it more common around here for a third grade kid to be maybe two years accelerated in math, then the kid suddenly raced through the math around age 12. I think it has a lot to do with brain development of abstract thinking skills.
