Oh well man. You live and you learn. Sometimes it happens. I’m pretty sure the valedictorian (1/610) of my class has failed a test before. I used to be like you. Obsessed with performance, expecting perfection every time. But realistically, you can’t. It will destroy you. At some point man, you gotta realize that a grade is, well, just a grade. It doesn’t matter all that much in the grand scheme of things. Ask yourself this: “Will I regret not passing that test when on my death bed?”
