Londons's taxi drivers are renowned for their ability to find their way around the capital without relying on a sat nav.

In order to operate a black cab, they must know more than 300 key "runs", and thousands of streets within a six-mile radium of Charing Cross, as well as countless places of interest, from hospitals to hotels.

Most need three to five years to learn "The Knowledge". But how well do you know London's lanes and landmarks? Could you be a London cabbie? The pass mark is 11/15

Once you're done why not test yourself on island outlines, the myths of air travel, Britain's seaside resorts, obscure capitals, cities from above, and the world's most famous paintings?
