Ally tries to hide her report card from her parents, but they find out. They are happy with many A's and B's. But wait- an F in Math? What? So they go see the teacher to try and straighten it out. They learn the teacher is strict and doesn't understand kids at all. So Debra and Ray work together to help Ally try to raise her grade.
An episode I can surely relate too, and I am sure a lot of other people can too. It was a really funny episode with a plot that is more then just about the adults for once
