Before getting into the car, I thought I had learned the instructor's orders, so once I started the car, my mind goes blank. I forgot what he had said to me altogether. The instructor kept repeating the word, “Speed up!” “Slow down!” “Turning left!” I was so much nervous that I could hardly tell which direction was left.
