Where does extra outside scholarship money go that isn't used in cost of attendance?

@mommdc my D has one that can. It’s a certain amount for four years but one year her own college would have absorbed it, due to a different one year outside scholarship, so she deferred it. She had the option to double it for the next year or defer the year to grad school. It very much depends on the specific scholarship. The one-time one that year wouldn’t let her do it.
