Yeah... don't mess up
Okay...lecture time! Your instructor won't let you take it unless s/he thinks you're ready. It does no-one any favours for you to enter and fail. Have you met your examiner? If not, try and do so before Monday, just so you know s/he's a real person!
Remember there's no hurry on the test (as long as it's not getting dark!). Take your time with the planning, and the pre-flight, but not too long, or the examiner might think you don't know what you're doing! Make sure they see you doing things, such as checking paperwork etc. Treat it like your driving test. Everyone knows you don't need to move your head much too look in the mirror, but it shows you
are looking. So, for example, after take off ask your examiner to sit back while you look past them... use your arm to push them back if need be
Keep a good lookout at all times, and let them see you do it! Oh, and don't forget FREDA checks... even though there's a lot else to remember. Jot it on your flight plan somewhere if you think you might forget.
If something goes wrong during the test, the most likely explanation is the examiner has done something on purpose. If s/he's recently pointed to something outside the cockpit s/he might well have turned the fuel off, or pulled out a fuse, or moved the DI while you're not looking. Don't panic! Check the obvious things first.
If you think you've messed something up, try not to worry. I think you get two goes at the handling parts of the test. You could consider asking to do something again if you're not too happy with it, letting the examiner know you realise there was a problem! Remember, if s/he doesn't stop the test, you've not failed! There's also the option of a limited pass (can't remember the official term) when you will be asked to refly part of the test on a later date. The examiner isn't there to catch you out, just to make sure you're safe.
Anything you're not sure about you should discuss with the examiner on the ground before you go. All that can be done on the ground should be!
And finally,
enjoy it!!! It's actually really good fun, one of the best flights I've ever done
