Did it recently mate, good course and as for hints and tips, get your nose into those PAMs youwill have an open book test at some point but it helps to have reasonable working knowledge of PAM 21. Also try and get a generic copy of a RASP as it will save you heaps of time when it comes to writing your own.
I'd agree with taking a few Nyrex folders for your range conducting notes. Try and take a laptop to word process stuff.
Its impossible to fail the course for anything other than safety breaches so just make sure you remember to give a full safety brief at the start of the range and to get a declaration at the end.
If the course is near to home, consider driving in every morning because there isn't that much to do in the evening.
Oh, and be prepared to listen to MPGS stories solidly for the duration of the course.
