If you don't like school, the first step is finding out why. You might not like school because a bully is bothering you, or because a kid you don't like wants to hang around with you. Or maybe you don't get along with your teacher. You might feel different or    1    that you don't have enough friends.

Sometimes it's a problem with your classes and schoolwork. Maybe the work is too easy and you get    2    . Or maybe the work is too hard, or you don't feel as    3    as the other kids.

If all of your subjects seem really hard, a school counselor can help you sort things out. Special help is    10    if you need it. Try not to let the problems go on too long. It's easier to catch up on one chapter than the whole book!
