I'm so jealous of people with a hard and fast deadline like that. I applied to exactly one school, this is my second year applying and the second year only applying to one school. Last year I had my rejection by March 16th. This year I just got an email last week asking for confirmation that I was still interested and what my inclinations were. That seemed like a good sign but, that was almost a full week ago, and I replied confirming my interest, got a reply confirmation from the admin, and haven't heard a thing since.
On the website it says they will continue until they have a full class of twelve. (They only accept 12 people a year) So everyone else will obviously have to make their decisions first. . I know I should just be thankful that I heard something but I was kind of expecting to just get rejected again. Obviously I got farther through the process than I did last year but seriously...I don't know how much more waiting and wishing and stressing my poor brain can take.
