Driving - juppun-ha-juubun 3-

I have graduated a driving school last Monday. I have gone there for a long time because I couldn't pass some exam. I have failed a exam for graduating once. There are few people fail it. I was one of them. There are some reasons I have failed. First, I run too fast. Besides I don't reduce a speed enough when I was in front of danger. It is natural I have failed. Second reason is that I can't do a correct judge. For example, when there is a man who riding a bicycle, I have to judge if I can pass him or not. If I miss then, I may cause a traffic accident.
