I wouldn’t expect a college that already awarded you merit aid to stack need based aid on top of that. Colleges base EFC off parents income because they expect parents to pay. Have your parents told you how much they’re willing to contribute?
You can only borrow ~$5500/year on your own. How much can your parents pay without borrowing? Will that and the ~$5500/year federal student loan cover the balance at the schools that gave you merit aid?
