xatknowledgequiz
Xat seems simple, but it may not be as simple as you think. Xat can be more complicated than a lot of people think. This quiz is sort of long, but you should get an accurate assessment of your xat knowledge, at least semi accurate.
Be prepared, this may ask some rather tougher than normal questions, see what you score, and see if you can get 100% without researching the answers during the test.
