Thats pretty harsh,so is this. My friends sister took hers today and the driving instructor told her to go left so she went left,but then at the last possible second he said 'oops wrong way go right' (this wasnt part of the test it was a genuine mistake) but she couldn't as it was a a roundabout and he failed her because of that,even though she just went round the roundabout to the turning he said.
How harsh can you get?
