Academic fit isn’t all you should be looking for. There are many characteristics for college choosing. Your student should be making a list of what is important to HIM regarding college. He will find other smart kids at just about every college in this country.
So…look at other things…size, location, weather. AP courses don’t matter as much as you seem to think. There are plenty of kids like yours (and mine) who got college degrees with very few AP courses.
