Did you explain to the examiner that you were doing the maneuvers EXACTLY the way you had been taught?

When I worked in training, if any pilot didn't meet standard, the first place they went to was not the pilot but the instructor. The instructor was debriefed and in some cases, it was the instructor who got an additional ride.

Second, the examiner may have been a dorko also so talking to him may be a waste of time. NO ONE should berate or talk down to someone taking a checkride. No one goes for a checkride expecting to fail and his attitude is also suspect. This happens.

Still, talk to the examiner and ask questions. You should have gotten a full and thorough explanation on every maneuver that didn't meet standard.

Is the instructor employed at a flight school or just an individual instructor. IF s/he is employed at a flight school, go talk to the owner. From hearing YOUR side of the story, sounds like you did not get your money's worth.
