So wish me all the best.
All the best!
Make sure you get plenty of sleep and arrive at the airport in plenty of time. This will get you off on a good footing and you wont be scrambling about looking for stuff. Get your route as soon as possible (if you havn't already been given it) and study it well for different landmarks on the way. The diversion will come on the second leg so take a look at likely places as you will have an allowance on your ETA of +/- 3 minutes.
EDIT: Might be a bit late now but I brought the POH of the aircraft home two days in advance of skills test and apart from the weight & balance and helping you with the general questions posed by the examiner it is actually a darn good read - a real page turner!! (Sorry if that sounds a bit sad but you will learn some stuff about your own plane that you never knew before every time you it; it shows how wet we really are behind the ears)
Keep it simple and keep it safe and I am sure you'll ace it so
best of luck!!
