"Our Committee on Admissions will review your application in the context of the overall applicant pool. In mid-January we will send a status update letter to each individual who has interviewed prior to that time, accepting a small number of candidates, declining some, and deferring a final decision on some.
We plan to complete our interviews by late February, and by mid-March we will send a second group of letters to all candidates who have completed the application process with us, including those who were deferred in the first round. In that second group of letters we will accept most of the entering class of 2008, invite a few individuals to take a spot on our waiting list, and inform others that we will be unable to offer an acceptance this year."
