I was scared spitless when I had my test. I was so scared/nervous I messed up twice. He said turn right I turned left, he said left I went right. I knew he had to think I was an idiot. But at the end he told me that as nervous and scared as I was he'd seen much worse. And that despite turning the wrong way twice I did just fine and I passed. I had built it up in my mind into this huge thing and then it was over and it was fine.
I'm sure you'll pass but more practice never hurt

Do you have to go to driving school or can you have a friend or relative take you out to some deserted roads and practice?
