This is very discouraging.
My only hope in all of this is that, from what I understand, they do not contact applicants prior to mailing out letters of acceptance or rejection. Whether this is completely accurate or not, I'm not sure.
When I was accepted to their Master's program, I only received an acceptance letter in the mail, no information via email or phone prior to. Though they may have changed this since then...
Do you know of anyone in the Dep't of Public Health Sciences that has heard back?
