Who was the commander? (You did agree that with the club pilot, didn't you?)
If you were the commander, then you were p1.
If a pilot from the club was commander and was not an insructor/examiner, then you were passenger.
If an instructor was commander, then you were p.u/t.
You are only p1/s at the (successful) conclusion of a test for a licence or rating.
That's as I understand it, but others will add their views and correct me if necessary.
