 529s aren't just for just tuition. You can use it for room, board, books, supplies, and any other qualified expenses at an accredited vocational school or college or graduate school in the U.S. and abroad. My son went to overseas, and so you can use it for an overseas program as well. This is the other big one, and this is certainly one I'm going to take advantage of. Excess 529 funds can be converted to a Roth IRA.
