Have you got what it takes to be one of the cleverest people in Britain - officially?
Mensa, the high IQ society, will be holding a supervised test session in Watford on Saturday, August 16, to give residents chance to find out their IQ score.
Mensa membership is available to anyone with an IQ in the top two per cent nationally.
The session will be held at Watford Central Library in Hempstead Road at 11am.
As well as finding out their IQ, those who take the test will also get a free personality profile from Mensa.
The chairman of British Mensa, Chris Tyler, said: "A Mensa IQ test is an ideal way to help you realise your potential."
British Mensa has 21,000 members of all ages and from all walks of life, who enjoy a varied social events programme and keep in touch through a monthly magazine, regional newsletters and more than 100 special interest groups ranging from classical music to chocolate.
