They move a bit slow. Just got word of an interview invite (sent on Tuesday via e-mail - just found out about it a few minutes ago). They assign you an interview date. I think I had my secondary in right before the end of January, so I assume that you should be hearing something soon. Best of luck!
I sent in all of my stuff in early september, took the august mcat and meharry told me that my app. was complete on Jan. 3. They still haven't sent me an interview and so I am crossing my fingers and hoping. good luck.
