CandidateX-
Self Confidence at OCS and TBS is huge. I would say the underlying theme in all the candidates we dropped is lack of confidence. "I can't do this" or "I'm going to mess up" will eat you alive at OCS. I don't understand why you are worried about being dropped from TBS, when OCS- whose sole purpose in life is to drop you- isn't riding as heavily on your mind.
Reading through your posts, you ask alot of questions to try and determine your odds of success at OCS, (i.e. Do athletes make it through/ what percentage make it). You are trying to make yourself feel better about the challenge by gathering statistics. You're not going to find much relief looking for numbers, it's just more junk to put in your head and give you reason to doubt yourself . Don't worry about whether you played sports or not, don't worry about whether you are a public speaker or not and don't think you will mess up- just go and do your best. At OCS you will be individually evaluated, and passed or failed on your performance alone. When you pass or fail it will be because of your performance, not because you are a public speaker or a high school athlete or because 90% of candidates with family in Walla Walla pass, it will be because you either performed or you did not. That being said, spend more time PTing, learning general orders, and relaxing, and less time spazzing out about obscure statistics. Like Crowbar said- it's football season!
