congratulations on your admit!
I also got admitted in to SUNY Stony Brook for MS in Applied Mathematics; I got so lucky cause thats the only school I had applied for.....I can give you some information about Stony Brook. First the CS department there is perfect, they have truly outstanding scholar like Prof Joseph Mitchell, Arie Kauffman, Steve Skiena...those guys are amazing in alrogithms and computational geometry...I am not sure if thats your interests...but anyways Stony Brook is good for CS....the only downside about stony brook is cost of living...its very High!!!!!Its in Long Island, its expensive

...but you are given money so don't worry about that...anyways hope you got some feedback
