moral dilema I have not done this but my question is this; Say I'm on the waiting lists at schools better than the one I was accepted to (phd program). The schools that accepted me want an answer by april 15th. The better programs that have me wait listed won't tell me until shortly after the 15th. My friend told me that I should accept and that if I get into a better program that I should just call the program I've accepted and tell them I changed my mind. I don't really feel right doing that but he assures me it's quite common. Is it a big deal? if I accept an offer and then change my mind a week later will I have done something wrong or is my self interest more important?
