<p>Hi maddenmd,
My son submitted for USC SCA two weeks ago. They only downloaded the supplement a few days ago. On monday, DS called the admissions office to check on letters of rec, etc, because he’d heard nothing from them. They picked up immediately and gave him a confirmation number/confirmed his file was complete. Yesterday he finally received an email confirmation, also. So I would call to put your minds at ease. First year using common app = some blips and delays on their end. DS said they were very nice!</p>
