I just interviewed there. They have a two-tiered deposit. $250 is due mid-December and The other $750 is due 2 weeks later. This is what the admissions rep told us. Total $1000!!
Admissions is on a rolling basis. Those accepted before November 15 have until December 14 to put down a deposit. There is a thread floating around about the AACOM deposit schedule if you wish to see it.
