I had extended driving lessons, and a lot of them because I am disabled, it took a while longer for me to get used to it, was going great and my instructor decided to put me forward for the test. The day came and he phoned me to say he was ill and really sorry but he couldn't go so he sent another instructor. I was totally off put by the new instructor and I had an hour lesson before hand, I couldn't do the most basic parking/reversing with her, I completely lost it. When the test came it was again a women. Suffice to say I was nervous again and failed on 2 points, not entering the yellow box fully and something else. Totally gutted by the whole day, from start to finish.
After a few weeks and a few more lessons my instructor put me in again, and I got a guy tester. The dude was so laid back and calming, talking to me about how I am etc put me at ease. Started test, I did emergency stop, parallel parking. Lastly I reversed round a corner and he said ok just have a minute and talked to me about news/weather/whatever, and then said you can drive back to the test centre now, it was only like 15 minutes if that, he told me as I pulled in I can relax I've passed. Completely different day to the 1st test.
