I recieved an offer of admission from the University of Alberta, which is great, but my problem is that they've requested I submit my answer by March 15th! That seems so soon, and I know one of the other programs I've applied to doesn't send out offers until April :S I'm not sure if I can ask them to extend their deadline, or if I should say yes and then cancel if I get into my first choice. Can I do that? So confused....
