Also if you want to go the extra mile, ask the instructor his weight, give him a detailed pax brief and good take-off brief.
Extra mile?? No, w&b and the briefs should be automatic. What I would say is to treat your examiner as a passenger who is asking to see certain aspects of flying, take the attitude that YOU are the captain (with the rider of course that if he calls "I have control" or TELLS you do do something he IS actually the boss).
If your instructor is happy then you should be ok.
Good luck and enjoy it
