Life doesn't revolve around my test scores. I'm gonna be fine. If I actually have friends who will give me a hard time about it, then they weren't my friends to begin with. The people who really matter don't care about my grades. They care about me.
Tomorrow, I have another test in another subject. I might do well on it, I might not. Whatever I get won't matter by June. You know what matters? Me.
And I'm a lot more fun than test scores anyway, no matter how high or low those scores might be.
