The quiz consists of 841 questions in several categories, named after various faculties of the University, such as Thaumatology, Arcane History, Dwarf Studies, and Oook. Each section contains a bonus question, and several ways exist to score more points for a question, many of them ludicrous. David Langford has intentionally not based his questions on the Annotated Pratchett File, a long list of Discworld trivia available on the internet. Nevertheless several items are in both the APF and the quizbook.
