Vote for BU, Boston offers more opportunities just because of its location. Kelley is a great school, but Indianapolis is nowhere compared to Boston. I personally doubt how much reputation Kelley carries outside of the state of Indiana or midwest. Just my two cents. Good luck!
thanks shashanghai, I've asked some natives, they place Kelley as a great bschool, but bu is just soso. and I'm still thinking about purdue.............
