Test
Robbo
Just relax on the day. Don't think of it too much as a black and white test. Examiners normally try and assess the general competance and not look for everything to be done within 100% accuracy.
Ask anyone who has done a CPL or IR to confirm they made no mistakes. I would assume the answer would be very few.
Just a tip or two from talking to people. Lookout, lookout, lookout and speed.
I am sure you will be OK.
