part 2
If / when you get through to part 2 and get onto the syndicate work, the biggest piece of advice I can think of is to be assertive. Don't sit back and let someone else take control of the group (especially when you're leading it).
The mistake I made when I came to do my task was not being 100% sure what to do when I got stumped by an obstacle. Make sure you have a plan of attack, don't leave yourself halfway through a task looking stupid.
If you haven't done this already then you're a bit screwed now, but be as fit as possible. Minimum is 9.10 on the bleep test, but aim for 10 or 11.
good luck
