I don't think this is the right forum to get advice on MPP programs but, as it stands, I think your profile is obviously not a strong one for a candidate for the MPP or MBA at Harvard. Read their websites, and you'll see their minimum requirements (for example at http://www.hks.harvard.edu/degrees/admissions/overview/eligibility#heading_01 ). There are several applicants for each seat at Harvard, all of whom meet their standards (with the exception of the odd billionaire's child etc).

Get your GMAT score and come back for other suggestions.

I sincerely apologize. The title of this post deceived you probably, i meant to write MBA/MPP or MBA/MA International Relations. I am interested in these joint programs. I have a raw GMAT score of 680.

And Thank you Mr. Duncan for your kind reply..

Your weakness is in your work experience. Students at Harvard have about 3.5 years of post-bachelor's work experience (work experience does not include internships, volunteer experience, etc.)

For an MBA program to be valuable, you'll need to have some reference, and that can only be gained through work experience. I'd recommend taking a few years to hit the ground before even considering an MBA program, let alone a dual-degree program. You can start looking at other, similar programs to see what's involved in the application process, what kinds of candidates they accept, etc:

Wharton - Lauder MBA/MA program
George Washington University - MBA/MBA in International Affairs
Chicago Booth - MBA/MA in International Relations
Berkeley Haas - MBA/MA in International and Area Studies

INSEAD and Johns Hopkins also offer a joint program that's pretty interesting as well.
