I don't know about other law schools, but one of the local ones (Hamline) has a very good program in Alternative Dispute Resolution. I took the certificate as part of my master's. It would be a good way for someone to learn a lot about law school, I think: the classes were basically taught as a counterpoint to law, have a lot of law students and lawyers getting their continuing education credits, and are really really useful even if you don't do it professionally. And because they're often used for CLEs, non-law-students can actually get into them.

I get told a lot that I would do very well in law school. I found from the ADR courses that a) I would and b) I'd hate it.
