I would confirm everything just said. Just be yourself. I like to think that I was an excellent candidate. But sadly I was not offered a commission.
My only real advice would be know your maths. Time,Distance calculations play a large part.
Also do it while you are young. I have now missed the boat due to age and its heart renching.
Also enjoy the mess. But don't be tempted to drink alot. You won't get much sleep on the old beds!!
As long as you have prepared well and you are reasonably fit. It will be down to your personality and the unknown factor.
I can say you will enjoy it. I met some fantastic people.
Good luck!
