School really plays an important role in our life. I like my school and my teachers. However, I think that sometimes we have too much homerwork. In my school lessons start at 8am. My school better than schools in other parts of the world. Most students live nearby. The average school day in my school is 6 hours. There are a lot of rules in my school.
