Depends on the school. My D auditioned for AMDA in NYC and was told she’d get a response in 2-4 weeks (yesterday was week 3 and she’s getting itchy). She received an acceptance from one school two weeks after she auditioned and was told by another school that everyone would be notified on April 1 (3 months after she auditioned). I agree this process can be infuriating! Best wishes to you!
