In reply to Philo22:
Loads of really good advice given so far. It's a training course, so although you will presumably have the requisite logbook experience, expect to be learning loads, and don't panic if other people on your course seem more advanced than you- everyone is at their own stage of gaining experience- its how much you take on board during your training that matters.
To that end, my main advice is to make sure you are as physically comfortable as possible during the course. It is exhausting and there is a lot to learn. Being cold, wet and hungry is not going to help so make sure you have plenty of warm gear, your boots are comfy and solid, your waterproofs don't leak, and take enough food. Grab every opportunity to eat when on the go, and get as much sleep as you can when you can. Be organised with your gear and bring spare stuff- extra gloves and hats are a must.
If you feel unsure about something ask your instructor- this is your first and probably best opportunity to clarify techniques and the syllabus requirements before you go in to your consolidation period.
My Summer ML training utterly transformed my confidence and self reliance. Afterwards I felt much more comfortable about bad weather and solo trips. Enjoy!
