Via @warpeddragon. Just found this really cool quiz on HelloQuizzy.com, that tests your alertness with some of the more easily confused English words (like affect/effect, their/there, who’s/whose). Given that we’re full-swing into the Nanowrimo season, I reckon this is one test worth taking ;)

And my results?
