I have to say, report cards are important because your mom or your dad would go crazy if they don't here on how there son/daughter are behaving, then that means that their son/daughter could already be doing wrong things, maybe. If I were to grade a student, I would depend their report cards on their behavior on the specific subject.Or maybe I could just tell the student personally, with his/her parents. This way the student can't hide anythin that they do in the public.
