Totally agree - as my instructor said, it as how you managed the situations that counted, I messed up a few things on my skills test but flew the aircraft safely, managed to find my way back to the home airfield and passed.
Main thing is fly the aircraft, navigate then communicate (that should be drilled into you) and dont be worried if something doesnt go to plan - if you are safe and carry on, its likely that you will get a pass with a long debrief. Try to stay confident dont get rattled if you go off track or you mess up the PFL. Just go back to flying.
The main thing is fly the aircraft and be safe and try not to get lost
Up to you, but my instrucor also told me to tell him what was going through my mind, so when I was trying to work out what town it was I was saying it out loud - he could then see my thought pattern, when doing the PFL I again said everything so it was clear what drills I was doing and what field I was aiming for - it helped me..
Good luck and enjoy - its the best feeling driving home after he gives you the thumbs up
