People can change. I used to get 60th place with 60 students in the room when I was in 7th grade. Now I'm in the first place in the class. I used to be very bad in everyway. I was bad in sport, music, art, and study.

Now I'm good in everyway. YOur child might get the same grade as your. When I get the worst gradein the class. My father didn't seem to worry at all. Maybe because he know that I will get good score later like him.
