Hopefully I can provide some info. Some may be repeated and if so, I merely support those that have posted it previously. Having been to OCS once before, I don't claim to know it all, but I will share what I do know. I attended OCS 190 in Fall of 2005. After being dropped at the 5 week boards, I enlisted in the reserves and have spent the last year going through my IADT. Anyhow...
-They do expect more from the priors, but at the same time, it seemed the priors had a bit easier of a time simply for their knowledge and already adjusted lifestyles.
-Read the links provided earlier, they are all good info. Expect PT to be worse than boot camp. Expect to be treated like a recruit once again. It doesn't matter what rank you are/were, when you arrive, that rank no longer matters. You are now a candidate and will be treated by the instructors as such. Also, do not flaunt your prior status or rank above other priors or fellow candidates. Be there to help guide, inform, and educate if you can... but try not to come across as superior. That is a good way to make enemies with fellow candidates fast, and you don't want that. It's a cuthroat world, because we're all trying to make it through OCS, and it's competitive. But at the same time, none of us will make it if we don't work together. Anyhow, I'm starting to tangent now.
-Definitely bring at least 2 but no more than 3 sets of civies. The set of civies you wear to report in, expect to wear them all through in-processing (2-3 days) without washing them. It's for this reason that I suggest 1 or 2 extra sets for when libo comes around.
-Bring your alphas as you may be able to have them altered rather than having to buy new ones. However, if you're driving, leave them in the car, if you're not, I would try to ship them so that you don't have to drag them through the seabag drag, and all that fun stuff.
-Be ready to answer lots of questions from other non-prior candidates.
Ok, I think I've run out of tips, for now. Good luck to all who will be reporting on the 20th! I look forward to seeing you all there.
