When you mentioned the examiner was weird, it made me think he was unfair. Some of them have it that they'll fail you from the moment they lay eyes on you. I dunno what it is, but I heard that happens alot with first road tests. It's not fair, believe me. I finally passed on the 3rd try.
My first examiner was an odd one, barely spoke above a mumble and at that time, admittedly I really was a horrid teen driver. The second time, I scored a 85 on my mock exam, but the examiner flew into a tirade as soon as we started the exam. I wish I had reported him. I was so traumatized I couldn't get behind the wheel for over 8 months after that! I finally got a fair and civilized examiner and he gave me constructive criticism at the end after I passed. I almost hugged him!
So no worries... you're probably a very conscientious driver but had an examiner with a weird attitude. Just take it again elsewhere, or ask for a different examiner. Good luck.
