Answer: if Cedric doesn`t like the class because he is bored or doesn`t understand he could go ask Mr. jacobs for extra help on assignments. He could ask if there are any youth groups that teens like himself are in and he could go make friends there. He could also ask his dad if he can visit his old friends in Chicago for the weekend and maybe that would make him feel better.
