I'm from the 5th district. I'll be applying for a nomination for USAFA and USNA for the class of 2015. There was a list a few months ago that shows 2-3 underrepresented districts in GA. 5th district was one, and I want to say 13th was another. I'll try to find the list. 6th district is one of the most competitive,covering most of atlanta. As far as outside of metro, I'd imagine 12th is pretty competitive since it covers Augusta which is pretty heavy on military with a few bases out there.
