Not up to how we go about putting link on so copy this address into you search engine.  It is a World IQ quiz and is very addictive.  You can split it in the world, capitals, europe, flags and many more.  It is very annoying as it is acctually good fun. I aint so good and have an IQ of 118 on the world level with a score of 543000 odd.  You might have to register but it takes seconds.

Try it and have fun.
