Just in case there's someone who doesn't know, I wanted to mention that you are required to put the "600" code on a separate sheet after you take the MCAT. When I took it last month, the proctors were totally clueless about this process. They did say that there would be a chance to have your scores sent to any schools that don't participate, but they had no idea about the osteo code. It's "600" no matter how many you are applying to. There isn't a list for every osteo school so don't sweat it when it comes time to fill out the paper.
