One person at my school last year got a letter from his med school a month before matriculation saying that they were withdrawing his acceptance, since he was holding a seat at another school! He DID pull out of the other school, so it was not true! However, this makes me wonder... If you accept an offer at one school, put down the $100, then get another offer a month later and accept that too, do you have to contact school #1 IMMEDIATELLY to withdraw? Can you hold two seats if it is early in the decision process, and you havent decided? Finally, HOW ON EARTH does a school know if you are holding a seat at another school?
