So I know May 15th is supposedly the deadline where people have to chose only 1 school, but what happens if they don't? Is the May 15th deadline one of those "recommended" rules by AMCAS or is it actually "required"? Will the schools pull their acceptance? How can medical schools ensure that people drop all but 1 school on May15th. I know if people get off a wait list post May 15th, they have like 2 weeks to decide or what not, but I'm just curious about before that.
