The map

The map itself, and every figure and source on it, is open to everyone. Reading case studies is free within a monthly limit, and one you have already opened never counts again. Choose a pin to see what a country has, or a day to see the map as it stood then. Choosing an exam board changes how cards are labelled and counted, never what you can read.

All time

One tick is one day. Magenta days published an edition.

Legend

  • A magenta pin marks a country with at least one case study. Countries in the edition on screen are named beside their pin, and so is whichever pin you point at. How many cards a country has is read out under the map.

  • Each tick under the map is one day. Solid magenta days published an edition, and choosing one hides everything published after it.
