Thanks stevep64.
It doesn't sound too hard, but I'm just wondering if what I think the briefing exercise is, is even close to the assessment item.
When I think of a briefing, it's usually where you're explaining to someone else how to carry out a procedure or task, so I'm guessing it's just a communication exercise, to make sure we can retain a few pieces of info & relay it to another team member...
Anyways, as you say, I'll find out on the day.
I think it wasn't curiosity that killed the cat, it was anticipation.
