QuietStorm, Aequitas is definitely correct. I can give you some advice on the application process and some websites to look at information but I'm not at liberty to discuss the actual course except for these points:
1) Drink lots of water
2) Be in great shape, physically AND mentally/spiritually (Mental preparation can be helped by say, rucking in the snow or something else that kinda sucks)
3) Don't quit. Don't "self-select" yourself out.
4) Do your best at each event. Once that event is done, focus solely on the next one
5) If you do your best everytime, peer evals will take care of themselves
6) The course always changes.
7) Have the support of your family helps, but remember, it's something that you must go forward with and commit to yourself, alone.
EDIT: And 8) Remember that SFAS is just Step 1 of a long process before you can even get to a team. Trust me, as I finish up another deployment, no one is more aware of this than I. A lot of people tell me SFAS was the easy part and I don't doubt it at all. I have a lot of work to do before I finally "arrive" at Phase II, and then there is still more to be done. I'm excited about the journey though and wouldn't trade the chance to complete the Q-Course for anything else in the world.
Good luck. I'll post a couple links here that are good-to-go for finding out more information (SF Recruiting, etc).
Thanks for the advice. Much more helpful than Aequitas post.
I knew you cant talk bout everything per the outbrief etc. But thanks for what advice you have given thus far!
