I've just received a letter for the alternate list ranking and its quite vague on exactly where I stand. The admissions committee says there's 147 students on the waitlist and I'm in the upper half. Does this mean I'm in the second quartile? How many quartiles are there? Has there been lot of movement in years past? "The Admission Committee and the Dean of the College of Osteopathic Medicine have completed file review of the candidates currently placed on our alternate list for admission to the incoming Class of 2012. The ranking is based on a thorough review of your application materials and interview. According to our review, Boyi, you have been placed in the upper half."
