I also applied to UCLA's MPP program -- it's very quantitative oriented (like most public policy degrees), but you are also able to access great practical experience. UCLA is in a great location, in one of the most vibrant cities; there are many great departments on campus from which you can take courses.
In the end, education is what you make of it -- you're not going to be anointed with brilliance or prestige because you attend X school. I think many folks on this board have a bias based on what they hear, an ego they want to maintain, or what arbitrary rankings tell them to believe -- the ultimate choice should be made by you based on the faculty available, funding, location, and other other factors personal to you. But UCLA is def a great opportunity, so congratulations!
I'm yet to hear from them -- did they call or email before you received your package?
What other schools are you also considering?
