Dispatch,
Did mine yesterday - plan it well, and try to relax and enjoy it. I think being safe is paramount, from what my examiner said - and be in command - take time if you need to to get yourself sorted out. Worked for me!
Holloway - strage that, about the RT practical - I was nervous as anything too! I think coz it's recorded, you know that any embarassing errors will be held 'for posterity' for a few years!
