Realistic: 3/8 acceptances.
Pessimistic: 100% refusals
Optimistic: 5/8 acceptances.
In reality I truly feel like I won't get in anywhere, but that's the way it goes. Only two of my schools are interviewing and they're both in the rejection pile, so I probably won't have any. One of my sure acceptances is based on the fact that I have TWO professors there who want to SHARE advising me, but they haven't got much funding this year. So I flip between being sure I'll at least get in there, and being sure that I won't because the money won't materialize.
I only need one. I'd like more, but one, please, come on, one.
