You should be keeping your file at USNA updated until they tell you to stop - either you have an appointment or are out of the running. Seriously, it could make a difference in your viability as a candidate to update your file, and might give you an edge over someone who is not doing so. Have your counselor submit transcripts, awards, and other recognitions through the rest of the year. It could make a difference to you. Best wishes in your candidacy.
