Bringing this thread back up, because I thought of one more thing I wish I had done. I wish I had spent some time at the beginning of my application process looking at scholarships. If I had it to do over again, I think I might have thrown in a Round 1 app to ASU/Carey in the hopes of a fellowship (I did the same for UCSD, and it worked out well, but it could just have easily not have), and I also would have applied for one of the JPMorgan minority scholarships/internships (for which the deadline was right around 2 of my R1 schools, and I simply didn't have the time to commit to it). I don't make a lot of money, and I'm going to be financing my education myself. Sure, I want to get in, but I also want to investigate as many scholarships as possible, and this takes time and preparation.
Also, for any future applicants reading, there are some things I did right: I applied to Tuck, USC, and NYU through the Consortium. I applied to both my reaches AND my safety schools R1, instead of the usual strategy of doing only highest-ranked schools first (I think this more than anything resulted in a fellowship from UCSD). I wrote the extra essay for the Haas Achievement Award. So all in all, I did lots of work on the money front...but of course, I could have done more.
