I believe most students are able to secure something by the 2nd or 3rd quarter. Very few have to pay their way all the way through. Also helps if you want to do further study beyond the M.S.
aet, I was accepted way back in early Jan but obviously couldn't make it to visit day being international. How did you find the visit day? What were the facilities like?
I doubt most admits were sent out yesterday. Usually takes a few days to filter out (from past years records). No clue about visit day - not mentioned on the website.
