Firstly good luck, secondly, it's likely that you will be asked to do something during the test that YOU know you could have done, or have done better during training details. If thats the case, if you recognise this, you should demonstrate you willingness to perhaps do that part the test/exam again. However, be warned, under the new JAR testing requirements, if you screw up your PFL on the 1st attempt, its curtain's as this is one part of the exam that you do not get a 2nd go at. Just remember the wind direction from your deaprting airfield, get the plane into wind as best you can, know your MAYDAY call, engine start checks etc.... pick a decent field and you won't go wrong! Remember, AVIATE, NAVIGATE, COMMUNICATE.
