Congrats on your acceptance! So does the letter say the deadline is Mar 12th? I wanted to ask this just because I also couldn't see the decision in the portal, although it shows "Decided". So I guess (although they didn't tell me this), I somehow got waitlisted, and if the acceptance deadline for you is Mar 12th then I might hear back next week once they figure out how many people accept/reject in the first round. I just really want to know approximately when I can know the decision since I really like this program but I also have to make decision for other programs as well.
Congrats again!!
