A HIGH-IQ Worcester mum will investigate the nation's brain power on a BBC television show tomorrow night.

Mensa board member Sylvia Herbert (pictured left) will appear on Test the Nation: the National IQ Test 2003, at 8pm on BBC1.

Last year's successful programme, which was watched by millions of viewers, was nominated for a BAFTA award.

Ms Herbert will star alongside psychologist Dr Colin Cooper in analysing the results of intelligence tests carried out on audience members and the public through interactive TV.

The mother-of-two joined Mensa, the society for people with high IQs, in 1992.

She was elected as a director of the society in 1999.

The programme, which took place for the first time last May, will be hosted

by Anne Robinson and

Philip Schofield.

Ms Herbert, a Severn Waste public relations officer, said the show was a real highlight for her.

"I'm really looking forward to taking part again," said the 54-year-old, from St John's.

"Last year, the atmosphere in the studio was electric - people are really excited to find out more about themselves.

"This programme offers a marvellous opportunity to bring the subject of intelligence to a wide audience.

"It is filmed live, which adds a little more excitement to it," she added.
