You will make mistakes - everyone does. The examiner is looking for a safe pilot who understands what they are doing, not a perfect one.
I was convinced I'd failed mine as the lovely Tom Dougdale walked away from the C150 back in 1979.
"Thank you very much. Very pleasant flight". (Tom is the definative gentleman).
"But did I pass????" (I had serious doubts).
"Oh yes".
