Some Advice before basic training (army)?

Ok so I just got promoted today to e3 and I am a little nervous about how basic is going to be. When I was meeting with commander I got some of the rank messed up so I am going to freshn up on that. But any other advice?? I am a big guy so I know I got to get my running on point, im 6'3 260 but mostly muscle (use play college football). All this army stuff is new to me so some pointers before I leave on may 8th which is next week. I have been studying on future soliders and know the , ranks, general orders, 5 risk, 7 values, solider creed, military time, formation. Anything else I should review more before basic. Oh an my basic is in fort benning I am 11x infantry
