When did you aim at the champion?

The best time is to be the first in chemistry in the whole school (the kind with full marks). To be honest, I really don't have any fluctuations. The most exciting ones are my mother and my teacher. The whole school held a parent-teacher conference to send good news to the parents who ranked first in each subject. My mother put the good news in the most conspicuous place at the parent-teacher conference. Later, my classmates told me that my mother's behavior caused strong discomfort to other parents. The teacher came up to me and asked me, "You are * * *, right?" Only then did I know that there were three classes to start. The teacher didn't even know my name, and then said in class, "The leaders of our class have all come out." .
