Here's my situation: I'd like to get a dual MPP/MBA within the next three years and I'm currently deciding between MPP and IR programs. But which should I choose? I'm interested in pursuing social entrepreneurship in the Middle East. I'm a manager at a social enterprise in the region now, and previously worked in a policy-oriented regional NGO (total of 4 years work experience). I'm in to UChicago Harris, where I could potentially get an MBA with the Booth school. I'm in to SAIS, which has an arrangement with Wharton. I'm in to Georgetown SFS, which also has a business school. I'm in to Oxford, which is a one year MPP program. I could apply to a range of business schools in the fall, and see where I land in the spring. I recognize that these are all great programs, and getting into their associated business schools (or any business school) is no guarantee! Some insight would be appreciated.

Here is my situation: I've been accepted to two top-tier MPP programs, but without any funding. I also got into a slightly less prestigious MPP with a $21,000/year scholarship. How can I best leverage my scholarship to get the highly elite program to offer me money? Thanks!
