Guess what. I'm a high schooler as well. And the fact that his grades are bad is common knowledge.
So young high schooler with poor grammar . . . apparently his grades are not common knowledge because I did not know about them. And, even if it were 'common knowledge' try to show some class and not bridge it up in a public forum.
Could it be that you are quite jealous of his excellence in wrestling so you pull this nonsense about his grades?
This forum is about wrestling . . . not report cards.
