Vegeta,
I'm not sure about other schools, but this is how MSUCOM does it (everyone else should be fairly similar).
At MSUCOM, they first take all the applications that they have and weed them out based on academic criteria only.
Taking those with scores which meet the minimal criteria, they are then evaluated and ranked. MSUCOM wants applicants that A)really want to go to MSUCOM, B)really want to be osteopaths (not MD wannabes) and C)have a good understanding of Osteopathic medicine and its principles.
Using A,B,C and academics, they give you a numerical ranking which determines your getting an interview. The higher the rank the sooner your interview. Since they are constantly recieving applications, the rankings can change every week. They make decisions on one day of the week (wednesday).
This is why it is more advantageous to apply early. When there's only 50 or so applications to review your ranking can't be any lower than 50. However, as the applications come pouring in around Nov and Dec, now your looking at a list that goes up to a 1000 or more.
Like I said, I doubt MSU is unique in their methods. I'm sure everyone else uses nearly the same system. I hope this sheds some light on the mystery of why some people get interviews and others don't. In the end it is purely a numbers game.
By the way, if your stats are good you should hear something well before Feb. A lot of times they'll schedual your interview a month in advance.
