Applied to SCCO, WU, ICO, PCO, NECO, mid-september, have interviews for all of them. Already had interview for WU and acceptance letter, next interview is October 31. My stats are 3.3, 340. Still dont know why everybody only puts there stats, because mine are pretty average, but I still got interiews to all the schools I applied to. I think a big part is how you write your essay, LOR's and how you sell yourself to the admissions committee.
As for the final decision, the admission committee meets agian, review all the information including interviewers notes.
