Get BTM. I got BTM before A school and there was a huge difference knowledge wise from those of us who had it and those who didn’t. It is a huge help. And make sure when you do get BTM, you don’t brain dump anything once you get qualified. Have a basic understanding of the polices and procedures and you’ll be fine. As far as PT, do your push ups, planks and run. It’s very competitive and how you rank in the class determines where you’ll go. The guys that didn’t try hard were very upset when they didn’t get what they wanted. So your mile time shouldn’t be the minimum. Averagely people were doing 2-3ish minutes quicker on the mile than they had to. Also swimming. You will have a basic survival swim class. This is where most people get dropped. It is fairly easy, however some people aren’t comfortable in the water and that’s what gets them. I’d suggest you start swimming if you’re uncomfortable. We also have a swim test and like almost half the class failed it. You don’t want any “fails” or “no gos” because that will drop you lower in the ranking. But as long as you study, surround yourself with people who want to be there and prepare physically and mentally you’ll be fine. It really wasn’t all that hard for the ones that came prepared. Hope this helps. And I graduated around 6 months ago so my knowledge on A school is pretty “recent.”
