Not crediting college courses I've already done because of a "rule"

It's English class... Seriously? T.T It's gonna be such a waste of my time.

Because I think I'm fine with the day to day conversational language, and it's gonna be on that first. Perhaps I could benefit from the second course on scientific language but even right now I can read scientific papers and understand the gist of it (Scientific American and such, even on astrophysics I can follow without having ever studied that.)
Sometimes I may have to look up a word here or there, generally colloquial expressions that I obviously don't hear out loud considering where I live.

I'm disappointed
