Hi there! I was also admitted to the M.HCI program. I was thrilled when I found out! Do you happen to know what the difference is between the Pittsburgh program and Dual Degree with Madeira program. I know in the latter you finish a semester later and spend 1 semester at Pittsburgh and 2 in Portugal... other than that, I don't know.
I also can't attend the masters admit weekend. Grr quarter system.
