Hello, army national guard split option question?

[Babba G]

Hello, I am 18 years old, was 17 when i enlisted in the army national guard. I completed basic training my junior year summer which was a total of 10 weeks, I am a 19D or Cav Scout, and they are usually OSUT and I am just nervous because I recently graduated high school, and am leaving for kentucky again to finish my cav scout ait after being away for a year, i can pass a 2,2,2 pt test and get 60% in all events, im just worried to know what its like to do cav scout ait after being away for a year. I heard many different things like I would have to start back in like the 5th or 6th week of basic, or do like 2 weeks of reception, how does it work? and if anyone who has done the same thing i am doing doing, could you please help me and let me know what to expect? i really need help on this
