More than likely that the last group will be 60 people divided into 2 groups. There is a rumor that they are having a hard time filling up the seats for class of 2016. The FB group actually has P1, P2, and P3 in it so not many seats were taken (but that may not be the correct number of people accepted, cuz I saw 1 person from the West Coast and we have 20 plus CAs in our P1). Not sure the reason why they have a hard time filling the seats, since they have 100 more applications this year (maybe they decide to pick and choose this year). So don't be discouraged if you're in the last interview cycle. Good luck.
