I was wondering how do the adcom decides who to accept at the last minute. I am still on the waiting list. I called that school last week and they told me that they are going to be sending the final rejection letters out this week and they also told me that last year they had to call 4-5 people at the last minute. do they reject everyone except for 5-10 people just in case or do they reject everyone and then if they need to call some back?
