Why am I so blimmin nervous about my bike test?!!?

[sofie b]

Ok, here's the lowdown. 28 years old, female,been biking it on and off since I was eleven. Currently ride a little teeny cbr125 and have run out of excuses about why Im not taking my test! Im perfectly confident on my bike and bigger machines, and have been told that Im a natural on a bike. Yet, at this grand old age (?) I still dont have the courage to take my full test! I get really nervous and the thought of pootling around whilst an examiner watches my every move PETRIFIES me!
Does anyone have any tips on what I should expect? Or more importantly, is there anyone who is as blimmin nervous as me?
I know. Im a pathetic wuss.
