Knowledge of London hospitals and public buildings: questions and answers
Based on OpenStreetMap map data (© OpenStreetMap contributors, live map data, read through the Overpass API) and one other source. Checked .
Practice for the points part of the Knowledge of London written exam, on hospitals, courts, town halls and government offices. We chose these places ourselves from OpenStreetMap (© OpenStreetMap contributors). They are not taken from TfL's points list, and the questions are ours, not TfL's. Every place is within six miles of Charing Cross.
Which street uses the street in the place's OpenStreetMap address. Postcode district means the first part of the postcode, such as W1J in W1J 9BR. Nearest is measured in a straight line, not by road. Places open, close and move, so check a current map as well.

Questions people ask
Are these the points in the real written exam?
We don't know. TfL sets its own questions and sets them out differently. We chose these places from OpenStreetMap, so learn the points you find on the Blue Book runs as well.
Why does an address here look different from one I know?
We use the address on OpenStreetMap. A large building can have doors on more than one street, and some addresses change. Tell us if one looks wrong.
