Try to get that third party info to Syracuse. You didn’t get a financial aid package…because your financial aid application materials were incomplete (NCP or waiver…missing).
But keep this in mind also…Syracuse is a great school. It is VERY expensive. But the school does NOT guarantee to meet full need for all students. You need to SEE their financial aid award, because it might just not be enough for you to attend anyway. That happens too.
But right now…you need to get the third party info sent in ASAP…
