Have you ever written an essay? Maybe in high school, university, or college? I have. I have never gotten 100% on an essay. I did get a 95% once in the 8 years of post-secondary schooling that I’ve done. Once. On a topic I loved. It never happened again. I am pretty sure you didn’t automatically assume that I am a poor student or writer. This is probably because it seems reasonable to you that I’ve never had a ‘perfect’ score on an essay. Even if I got 75% regularly, you probably would still  think I was a pretty O.K. student.
