O.M.G.
Guys, you need to get a grip, for the sake of your own sanity! I'm sure the RAF will have told you where to go, when to report, and what to bring.
Here's a wacky concept, why not follow your instructions exactly and then take everything as it comes. So what if the DS raise their voice at you after an inspection. Learn from it, do it better next time. Simple. Oh and don't whinge or give attitude, unless you enjoy pain (extra phys, not beatings!)
I managed to get through 3 boot camps (OCTU - Henlow, Met Police - Hendon, ITC - Finningley) with no preparation other than what was officially recommended.
And in later years, when deploying on Ops, everyone followed the Admin Orders in terms of kitting, medical, paperwork requirements etc Anything else was just personal preference and to make life more comfortable.
What I'm saying is, go to Halton, give 100%, and take it as it comes. Otherwise, you'll just over stress yourself, and put yourself in the wrong frame of mind to succeed.
Oh, finally, enjoy the experience and very best of luck. Just remember, it's not the real RAF.
