your DS could reach out to the cadre at his top choice, share he received a scholarship, and ask if they have any pull with admissions or have any recommendations. For apps already filed your DS could call admissions to share these details. Annually there some kids who make this call to every university and imply that the one they are speaking with is their number one. Just all those considering doing that please be selective and act in a manner your future officer self would be proud of. It’s not all about bragging rights and it puts a bad taste i the Roo, PMS etc mouths. Some schools can and do help, some will not. I see no harm in noting In The app that he has a scholarship if it’s just added without fluff or pomposity.
