Hey SR0304,
I am one of your fellow acceptees for UCSD. And just as you are, I am fairly juiced! I have been scouring the internet looking for funding and cost planning myself. I also am really curious about the questions you have, too. There is little information about the San Diego fellowship, I believe it is a fairly competitive fellowship since it is campus wide. I wonder if the department guns for as much of that San Diego fellowship as possible because of the benefit the department has in getting a large chunk of their cohort taken care of by the system instead of the internal budget.
Also, it seems in general that UCSD carries a larger cohort. I wonder if this is good or bad from a competitive standpoint? I am a born and bred midwesterner and am doing my MA in the South, so the lack of winter and proximity to the ocean is a serious serious bonus I mean don't get me wrong I love our lakes, but it just seems so tempting and also the faculty is a great fit for me.
