I took one of those online grammar tests

...so let's see if I can post the results here.

English Genius You scored 100% Beginner, 92% Intermediate, 100% Advanced, and 82% Expert!

You did so extremely well, even I can't find a word to describe your excellence! You have the uncommon intelligence necessary to understand things that most people don't. You have an extensive vocabulary, and you're not afraid to use it properly! Way to go! Thank you so much for taking my test. I hope you enjoyed it!
