The highest you can rank is SPC. If you have any college, tell them, for every [certain number] of hours you have you get rank. Take the PT Test.. its a 2-mile run, sit-up and push-up event. You have to meet the Army Standards as if you were graduating AIT... so its like [for 18-21y/o males] a 15:00 two mile, 54 sit ups and like atleast 42 push-ups. If you can pass that, get a rank. And if you recruit someone then you also get rank. I entered as a PVT and im a PFC... its not worth waiting.... Do all you can now.
