Grades at school are often top worries for kids. If you're worried about grades, ask yourself these questions:

★ How do I get ready for class? Do I go over my notes even when there isn't a test?

★Do I have a good place to do my homework?

If your worry is about a fight you had with a friend, you might write down all the things you could do: write a note to him or her, invite him or her to a basketball game, say sorry to him or her, etc. Once you have a list of things you could do, you can choose the one that gets your friend back.
