I know that Arizona used to call everyone who was accepted. I'm not sure if they still do this because the admissions chair is different now, but they usually only accept about a third of the class on December 1st anyway. If they don't call you by the end of December 1st, I don't think you will be in the first set of acceptances. I probably wouldn't call until I was accepted to other schools and nearing my deadlines to pay them money to hold my spot. If you are supposed to send Nova a thousand bucks in a week, but you would rather go to AZ, I would call to tell them your situation.
My advice - don't call AZ unless you are about to donate a thousand bucks to a lower choice school. I still had to though. You're welcome Nova students. I hope you are enjoying my donation to ensure that I would be at least be attending A dental school.
Good luck tomorrow
