YOU can find out your IQ in Cardiff on Saturday, February 28, when Mensa will host a supervised test.

The test will be held at The Big Sleep Hotel, Bute Terrace at 10.30am.

Tests can be booked at www.mensa.org.uk where there is a choice of puzzles to help exercise the grey matter.

The free online workout, which involves 18 questions in 15 minutes, will give an indication of how well you would score in a standardised IQ test, and there are regularly updated brainteasers and a monthly fun prize puzzle.

The supervised test costs £24.95, including a free personality profile, and must be booked in advance.

To book, visit www.mensa.org.uk/iq-tests, call 01902 772771 (select option 1) or email bookatest@mensa.org.uk

Everyone who achieves an IQ score within the top two per cent of the population will be invited to join Mensa.
