Congrates! For what its worth, here is my DS's experience. His university pulled back the entire merit grant they had awarded him based on his financial aid application once his four-year full tuition NROTC scholarship kicked in -- he was not allowed to keep any of it (and when added to his NROTC scholarship it would have been excess over the cost of his attendance anyway). It made sense to me, because with a full ROTC scholarship, your financial need is substantially different -- the economics a university uses to calculate your financial aid package is no longer applicable once you have a full ROTC scholarship. However, my DS's university did very generously replace my DS's merit grant with their own NROTC Room and Board grant, which paid for half of his room and board, so it wasn't all bad. And my DS was allowed to keep the money from the several local scholarships he was awarded at the end of his senior year in high school -- these were scholarships not associated with his university. He was able to use that money for the rest of his room and board that the university's NROTC Room and Board scholarship didn't cover, and then carry forward excess from those scholarships into his sophomore year. So, amazingly, he still has a little bit of a surplus in his university account!
