I failed my first test for a stupid mistake as well, I had 1 serious and 3 minors. 2 weeks later I took my second test (last Tuesday) and I had the same examiner - he remembered me as well 😂 I passed that one with no minors, and now I forget my first test even happened! I was in the exact same position as you 10 days ago, I thought I had a good test first time and I would never get as good a chance again to pass, but I did!! You just have to believe in yourself as cheesy as it sounds
