I was in session 1 last year and received my appointment to c/o 2021 a few months ago and you will see some things on the internet about how ss doesn't affect admissions. I can tell you pretty frankly that isn't entirely true. At the end of my week we had a meeting with our squad leader one-on-one and she took notes. It was about our experiences of the week, will we still be applying, what is our motivation for applying, and similar questions that you will hear a thousand times. But leading up to that throughout the week there were more subtle evaluations. How you handled mock I-day and the endurance course. Did you follow directions or where you constantly creating problems. Honestly, if you want to be there and you feel comfortable you won't have a problem. I went just to see how I liked the academy and had some fun and it worked out for me. Just be yourself, it's not high pressure or anything just relax and get the full experience. Talk to as many people as possible and participate in everything.
Also weird tip but you only have three sets of shorts while you are there. Use one for Pep and let them dry and wear a clean pair to classes, and I would think about wearing those same dirty shorts to damage control because they are going to get soaked. Juts be mindful because you don't have time to do laundry.
