World War Two

A global conflict, 1939-1945

The deadliest conflict in human history, fought across every inhabited continent, and the one where the distinction between soldier and civilian largely disappeared.

The unit covers the causes running back through the 1930s, the main theatres and turning points, the home fronts, and the Holocaust - treated as its own subject rather than as one campaign among others, because it was not a military operation.

This unit breaks down into 20 short steps and 120 questions, starting at difficulty 1 and building to 3. Below you can see exactly what it covers, how the path is structured, and worked examples with explanations.

What this unit covers

  • Causes of the War
  • The Holocaust
  • Key Events
  • The Home Front
  • The End and Aftermath

Where this fits

Reads directly on from World War One. It sets up The Cold War, which begins before this war has finished.

Where people slip

Appeasement made sense to many people at the time, given living memory of the previous war. Judging it only with hindsight makes the decision look stupid rather than tragic.

How the unit is structured

World War Two runs as 20 short steps that unlock in order. 15 are practice rounds and 5 are challenge rounds that pull together everything before them. Questions start at difficulty 1 and climb to 3 as you progress.

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.
