For the most part my son covered the basics in an intro email (GPA, test scores, metrics, schedule, etc), so no need to ask about that stuff. Mostly they asked how he's playing, what part of his game is he working on (be prepared for a long discussion on specifics if he says something like "my swing" or "my throw downs", who else is he talking to, would he consider their school, when does he want to make a decision.
