I would apply NOW!. Last year I had everything completed in late january and i thought I was gonna surely get a spot somewhere. I waited, waited, waited and got nothing. So when i finally took the initiative to call the schools they told me the AAMC never sent my info to them! SO i had to hassle the aamc mmep people. So for instance at Columbia they choose their students from the first 500 that apply. The rest of the batch is kind of like a waiting list if people begin to chose other sites. So i got dumped there and at Yale. Thankfully, there was space in the NJMS program which i took part in. I loved the experience. The school was great, it was close to my family in NJ, and I met my current girlfriend there! How nicely things worked out. Anyways, like i said, apply now before spots begin to fill.
