I scored 200 on this year's college entrance exam, and I turned the whole school upside down. This was my third time taking the exam, and my score had been switched every single time. I called out to the police: "I want to see the person who switched my exam papers within 30 minutes, or I'll do whatever it takes." Countless parents collapsed to their knees, cursing me for taking my anger out on innocent people and begging me to spare their children. But I called out calmly, "I only want the person who switched my exam papers." I knew the person who switched my papers was somewhere in this school.
