Well, I am not sure about mathematics. May be a completely different game. But, it is still *possible* some schools haven't made any decisions yet (this is why this site may help, because you may know). Also, you may get a thick letter in April if you are secret waitlisted and someone else declines. That is, they may wait to tell you yes or no until they know if their top choices are coming or not. And, it could be that there is an applicant or two who are holding spots at a few schools and will eventually reject offers opening spaces. So, do not give up hope until that April 15th deadline that many schools share. Also, if you have no offers by then, it is possible schools will contact you after that if they have neither accepted or rejected you. Chances? It's like telling a dying person. You never know. You could die tomorrow (be rejected everywhere) or live a long and prosperous life (get a great offer!). Good luck and remember that you may have to unfortunately wait until others make their decisions to know.
