Hi.
I am also deciding between this school and GWU Elliott.
I was accepted to Georgetown without any funding and since I know that I'll be doing phd after, I'll probably go to a school that costs me less for masters.
However, still deciding!!!
Definitely USC if money is an issue. TA Fellowships are always hard to get. If not its really up to what you want to do in the future.
California versus D.C. it is a hard decision!!
