@nprofile1q... I did do some training for the advanced test (I didn't quite pass, twice, because driving under pressure for 90 minutes).
So I know I am a reasonably good driver. And my instructor did say I started pretty well, and was up to the standard just about.
But that is becasue I wanted to see how good I was, and how I could improve my driving. Not because I made the assumptions that I was some sort of perfect driver.
