I failed my first test because the examiner told me to take the wrong turn, me and my instructor argued with him (As i was allowed my instructor in the car). Got 2 minors and 1 major, i had 3 Point turn and reverse around a corner.
Test #2, passed with 1 minor, had pay park and parallel, test is an allocated time slow of 45 mins or so, the examiner ended my test after 17 mins, saying "No need for you to continue son, im happy to tell you that youve passed"
The first instructor was a dickhead, but the 2nd examiner was a woman who played COD, so i got on with her.
I also believe in them having to fail so many people per year, Think, if they passed everyone, the roads would become clogged, costing the government money to fix the roads/improve them.
(PS, im from mid Scotland)
