Just treat it as another lesson
Er, no.
That's the thing that I found most disconcerting on my test - in previous lessons the instructor had told me what to do, where to go etc. Being told by the examiner "go somewhere suitable to show me some stalls" was a new experience that I wasn't prepared for; although I succeeded in finding somewhere high enough, not above something daft, not too close to cloud and so on, this wasn't anything any instructor had ever asked me to do before.
