THE world's oldest high IQ society will hold a test session to seek out Oxford's brightest.

Mensa is to host a supervised IQ test session at the YHA in Botley Road at 2pm on Saturday.

Anyone who achieves an IQ in the top two per cent will be invited to join the group.

British Mensa has about 20,000 members but there are more than 1.6 million people in the UK and Ireland who are eligible.

The test costs £24.95 and must be booked in advance at mensa.org.uk/iq-tests or by calling 01902 772771

Mensa was founded in 1946 in Oxford.
