The part of the test where you have a ridiculous # of questions to answer in a matter of minutes is to see if you would make a good staff member, AKA pencil pusher. I scored very high in electronics and mechanics, I didn't enlist, I was a junior in high school, boy did all the armed forces want me after that test, I recieved letters for years, even found me when I moved out. There is a Marine motor pool in Knoxville, that is the branch I would join, no interest in the Army, but the pay is better in the Air Force.
