Aim Point, Aspect, Airspeed
Unfortunately getting in is the easy bit (It took me a few goes as well). Not sure what the scrub rate is of late on the courses but it is the reality of military flying training. You will be told on your induction day that not all of you will still be here at the end. Very sobering. Positive attitude, motivation and hard work will help get you through. Sometimes a bit of luck as well. You seem to have done some relevant prep which is good.
If it doesn’t work out for what ever reason, don’t fret. The GA scene is actually getting better and better. Both avenues are rewarding and you’ll meet great friends along the way.
Good luck with flight screening. Work hard and enjoy the experience.
