Let me guess. You’re the person who secretly judges her friends for confusing who and whom. You’re also the person who answers, “wat r u doing tonite?” with a perfectly spelled sentence, complete with punctuation. I won’t even get you started on that Facebook status your friend from college posted that’s rife with errors.

There’s no shame in geeking out over grammar. In fact, from one grammar nerd to another, I’m always happy to meet other people who obsess over it as much as I do. (See this for further proof that I am, indeed, obsessed.)

So, treat yourself today by taking five minutes to complete this awesome grammar and word usage quiz from our friends at Contently.

Warning: It’s not for beginners. And remember, winner gets bragging writes (consider that your warm-up).
