I am undesignated and I joined to become an aviator (does not have to be jets). I just got to the wasp in norfolk. I did not do as well as I could in high school. I am wondering if i screwed up not researching it more before enlisting? I know I can work my ass off to get a good sta-21 app. together. is being 20 yrs old to late? where should I start?
