The suggestions above regarding contacting Emory directly is best, but here is a little extra input from my experience in case it gives you some insight into your situation.
Cost of Attendance at most universities include 1) Textbooks and supplies 2) Transportation 3) Personal Expenses.
For example: if your Direct Cost (that’s usually only tuition and room/board) is $21,000, and your college’s COA includes those other expenses listed above and is (let’s say) $25,000, the school will disburse scholarships/aid up to that $25,000 amount (or whatever your college’s COA may be.)
If you have aid in excess of COA, they will (likely) first reduce loans, then work study, then federal or state aid, and then scholarships.
Sounds like you are funded by all scholarships, so if your total scholarships are over what they consider COA as you say, you will likely have to just give the excess up. They can’t legally give you money for school beyond the COA.
