Yes, you've taken grammar and vocabulary tests before. What makes this one different? Well, it's based on TRUE-LIFE EXPERIENCES. This test captures the full EMOTIONAL scope of proper grammar and word usage, as each and every question derives from an error that causes me PAROXYSMS OF RAGE, because I've corrected it at least 300 times on students' papers. A few of the questions are especially notable as spelling errors that won't be caught by any spell-check application.

P.P.S. If you're worried that that introduction might indicate I'm likely to hurt someone, do a side-by-side comparison of my profile and note the violence score.
P.P.P.S If you write bad I'll still love you, but if you write well, I'll love you all the more.
