What will you do when you know your grades and are laughed at by your relatives?

I think when my grades are laughed at by my relatives and elders, I will work harder and won't let others look down on me easily, because I think my grades are really poor and I have some problems myself, and the ridicule of others is understandable. I want to face the ridicule of my relatives. I must be more confident, more motivated and more diligent, and then let them change my mind and not let them look down on me. I miss everyone.
