I've applied for the math PhD program for the upcoming Fall 2018. The schools I applied include Brandeis University, University of Tennessee, York University and Simon Fraser University. Since it has already been about 10 weeks from the deadline and I have not heard any news from them, I would like to ask anybody with experiences of applying the math graduate program of the above schools: What is the average decision time of the schools I mentioned?
I am struggling with this since one high school in my country is inviting me to be their math teachers, and I need to sign a one year contract if I accept. It's impossible to let them wait for months for my response. Or anybody can give me some advise on this issue?
