Make sure you let all your instructors in advanced know that you had jet grades but got screwed by the Man. Then, if you make it through, be sure to tell everybody in your community that you had jet grades and shouldn't be stuck there. Having said that: if you think my response makes me sound like a dick, imagine what you sound like. Learn this now because it will be useful your entire career: the Navy owes you nothing - whether you worked hard for it or not.
So, in all seriousness, shut your hole and be grateful - being a whining tool now can follow you all the way to the Rag and your first tour.
EDIT - By the way, I do know that comes off as harsh, but he needs to get over it before he damages his reputation in his new community. Students sometimes don't realize that instructors talk to each other across the pipeline, but they do.
