I applied to 5 grad schools. They are all schools that I would enjoy going to. Got an offer of acceptance from one of them and I accepted it. To be honest, I didn't think I would get accepted anywhere so I got excited and accepted the offer. However, 4 other schools won't respond till late March and April. If for some reason I get accepted to the other schools can I reject the offer? I really like all the school that I applied to and I honestly did not think I would get accepted elsewhere.
