Call me ignorant, but what is the significance of May 15? Is it when students have to decide for good where they are going so people can come off of the waitlist? I keep getting information from MCP Hahnemann, where I interviewed and was rejected, about their Master of Science program. But, since I was accepted to a few schools, I haven't looked it over real good. It seemed like a good school when I was there, but the tuition isn't good. You may want to check it out if you don't get in, but I would look into MS programs real soon. I think its a great idea especially if there is a tie to the schools medical school, but I know there aren't at many of them. Some of them have a great track record, like Columbia U (costly and competitive I hear). Good luck on admission.
