Are you already an officer, or are you going through WOCS as well? If going through that too, you'll have anywhere from 18-24 months of training at Rucker, depending on airframe and training bubbles.
It is a full time job. When you're not in class, you're on the flight line. When you're not at either, you're studying. My person study habit was Sunday afternoon till I went home on Friday, studying anywhere from 1-3 hours every evening. Friday afternoon through Sunday afternoon was mine to do as I wish. Then back to studying.
Focus on Rucker. There's very little fluff that you can forget about. Do not fall behind because you're shooting for goals years away and mess up what is right in front of you. Do not show up at your unit weak in academics, it'll hurt your progression and they'll rightfully progress and give more hours to those that know their stuff. And always be ready for a no-notice 5&9.
