Before you start

  1. 1.

    You do not need an account. Practice, mocks and flashcards work straight away, and your progress is saved on this device. An account only keeps it across devices.

  2. 2.

    Every question shows where it came from: a past Economics Olympiad paper, a past IEO paper, the practice bank written for this site, or a question sent in by another student.

  3. 3.

    Free response answers can be marked for you. AI marking works against the mark scheme and is labelled as possibly wrong. With an account you can send an answer to a human marker instead.
