I agree with the others.
You are probably doing your most accurate flying at the moment, sloppiness comes with experience, but try to resist it.
Your instructor must think you are ready.
On the day give yourself plenty of time to get to the airfield, take it steadily without russhing and stay on top of the game.
I have spoken a mantra to myself in the past in similar cicumstances, "I am a pilot, I can do this, I am a pilot..."
Seems to work for me.
If you cock something up, don't let it keep playing on your mind destroying your performance. This is common in flying and causes accidents.
Put it behind you and get on with your job as a pilot. We all have our "brain farts".
Enjoy showing your skills and here's to that greaser on returning!
