Always call and check the details with the university you are considering. My oldest went to a Washington University in St. Louis on a type 1 AFROTC scholarship. The school tossed in free room and board, so my son paid $0. My second son received a AFROTC type 2 scholarship to the same university and they refused to make up the tuition difference, so it would have ended up costing $25,000 a year for us. He also had an Army scholarship that kicked in full tuition after the first year. WashU refused to cover anything in that case. They said the offer of room and board was an incentive to attend, but if the student was already there they didn't need to offer anything.
My second son decided on a school in St. Paul. This university's policy is that if you have even a $1 military scholarship, they will pay all remaining tuition and give free room and board.
My point is: don't assume anything! Get information directly from the school you plan to attend.
