If a bully bothered me at school, I would first go and tell an adult. You want to have somebody to trust, like a teacher or your parents/gaurdians. After you tell the adult, and nothing is resolved, go up to the Board of Education. If that teacher or principal didn't do any thing you can make a formal complaint aganst them. When you go to the BOE, talk to the superintendent, and see if the problem can be resolved there.
