My name is Anna. I am a 16-year-old student. I was used to be my teachers’ pride during junior high school although I often beat my classmates in all kinds of tests. All the teachers believe that I could bring glory to myself and to the school by enter the best senior high school. I didn’t let them down. I made that. Since I entered one of the best high school, I have lost all the glory and attention. I’m just ordinary student. Many things in the textbooks are extreme hard to understand. I found math especially difficulty. I am not a lazy student. I even study hard than before.
