I'm in 20' and I can tell you that everyone comes to R-day with the same exact fears. I had some serious anxiety of just not being good enough or not being able to catch on. I thought I was going to be the most out of shape, the dumbest, whatever "est" you can name. I fell out of two hill runs during BEAST, I had a horrible first APFT, my pullups were weak, and I sucked at everything from remembering knowledge, to land nav, to qualifying on the range. I lost my knowledge book half way through, found it, and almost lost it again. I carried around several rocks so I could stop forgetting things and I even lost some of those rocks. I saluted a sergeant. I got dropped about 6 times. I fell asleep during Briefs. BEAST makes you act unnatural. The easiest things become the hardest. Realize you will make several mistakes and they expect that. Your chain of command is other cadets and they are learning just like you are. Also, your classmates will be the same, sometimes better, sometimes worse. Relatively almost everyone comes oblivious to what is going to happen. Beast itself and West Point seems daunting before you get here but I can assure you that once you get here and finish BEAST, you find your niche and you blend in. Do the best you can in all you can for as long as you can and you will be fine. All BEAST is is just showing up and doing what you're told. You'll do things and wonder why you're doing them, you'll hate some things, you'll love some things but just do it. You don't have to be a know-it-all or a complete PT stud. Some kids say BEAST was easy and some say it was one of their worst experiences but one thing that is certain is you'll finish it, be better because of it, and almost forget about it once school kicks in. Good luck. This might not necessarily be consoling or what you want to hear but there is no uniform experience for everyone during BEAST. Just because a kid said it rocked and it was soo easy don't assume that'll be your experience, same goes for it being the worst thing ever.
