My son applied over 2 weeks ago, and although he received a confirmation from the Common Ap, he has not received an email from Tufts. He doesn’t know whether to check in with admissions or wait another couple of weeks since it is very early in the year?
His application was probably the first they received 
I’d assume that since it’s the last week in August, the office is probably on a break until after Labor Day weekend. I’d wait until at least next week. Classes start right after Labor Day.
