One option would be to trade in the 3 yr AD to a private college for a 4 yr scholarship to a public college. This is a viable option if there is an appealing public school within the same battalion.
Thanks for that response Marist ! In this case we have dependable info that his letter will include a 3yr to both his #1 school choice ($20,000 yr) and his #2 choice ($28,000). Both are in state public schools. Can we accept #2 and trade for #1 though it's on the list already? You're right though, 3yrs at #2 is equal in cost to 4yrs at #1 choice. Can our ROO make that case for us? I guess we accept #2 and then see if it can be traded later for #1 for 4yrs. ?!?!?
