In reply to Simon_87:
I thought it was a hefty jump from ML/SPA, having already done lots of multipitch climbing to a reasonable level and having quite a bit of knowledge on rescues i thought i was mostly there and would just be fine tuning things.
I was very wrong (in a good way), as i learnt absolutely loads in the training course (and the assessment course). I was sort of surprised how much it actually covered, and it is really crammed into the 9 days. Awesome course and highly recommended.
Definitely copy what Jez said about being a psyched climber will get you a long way towards it. A lot of the course/qualification is knowledge. Where certain climbs are, what a certain rocktype is like, what is the environment like in those places, who those places would be suitable for and teaching what aspects there. And getting into a lot of mini faffs so you can learn from them (hopefully not too many epics though :P).
If you go lots of places and do lots of fun things in the mountains, you'll be well equipped to get the most out of the course!
