Tell me how it changed from mediocrity to Excellence.
When I was a sophomore, I was always the kind of person who didn't study hard. In my teacher's words, I just didn't take it to heart. When I was in the third year of high school, my mother was ill and hospitalized. Then she called me to the front and said she hoped I could get ahead. Then she suddenly woke up and began to study. I'm smart, and it didn't take me long to keep up with it, and my grades are good. I was admitted to a key university in Beijing.
