I second the suggestion of majoring in SCM and minoring in political science (or, for law school, philosophy or English - business majors get less exposure to reading/writing so you need to compensate for that with a reading/writing heavy minor).
What’s the net cost at each of the three universities?
(To figure out net cost, add tuition+fees+r&b, and subtract grants/scholarships you got. Do not subtract any loan).
