Are you sure about that for the AAMC chart? I was confused about the dates too, but if you go on the AMCAS site on the top right corner, it says the 2015 AMCAS application (the current one) is for people who will matriculate/start med school in 2015. So on the AAMC chart here,
https://www.aamc.org/students/download/398586/data/mcatexampolicy.pdf, I'm assuming that the first column (says "2016 AMCAS application cycle") is for students applying in June 2015 (which is what I plan to do) and hopefully starting med school the following year in 2016. Please correct me if I'm mistaken! I'm taking the MCAT in January 2015 and this whole concept is such a hassle at this point.
