I got an unofficial acceptance and funding offer from UIUC during the first week of January with an official offer following during the last week of January. It seems that their admissions are pretty staggered so if you haven't heard yet DON'T LOSE HOPE!!!
haha. It seems MIT was sending out a lot of love on Valentine's from what I've seen on other forums. They certainly got their feelings across to me. NO THANKS!
A friend of a friend of mine just got their acceptance to the math Ph.D. program at Caltech. I have yet to hear anything as far as my own application is concerned.
