Having undertaken my skills test back in June I don't think the examiner is there to catch you out. My advice would be to verbalise everything ie when he asks you to demonstrate a clean stall, talk him through your pre-manouevre checks, then say "throttle closed, stick back, speed reducing etc etc". That way he knows you have a routine to follow. And as bingofuel said, enjoy it. Le tus know how it goes.
