Is there an intelligence test TV writers have to fail?

Someone that got into AP English or someone from a smaller school district might have seen more of grammar in their curriculm than those in larger school districts (A or larger districts).

I disagree. I had AP English in high school in a smaller school district and they assumed you already knew grammar so they didn't bother with teaching it at that point. The only time I ever learned English grammar was a smattering here and there when I was taught Spanish, German, and Russian. None of my English courses, including literature ones, ever taught grammar. I don't see why you think smaller vs larger districts would cause a difference.
