Going back to the original question for a second, I had my Ohio State interview yesterday, and in the orientation beforehand the Dean said that all the American schools have an agreement that they can't make you decide before April 15. She also said that sometimes (rarely, but it happens) schools have tried to tell students they have to decide before April 15. She said that is DEFINITELY not allowed, and that if that happens the school should be reported. I'm not sure who to report it to, but I'm sure that the Dean of any of the other schools one has applied to would be able and willing to do something. They said at OSU to feel free to contact them if that happened because it's a major no-no.
