Where do the answers come from?

Every fact on a SESK card comes from a source, and cards are checked and approved before players see them.

To see a card's sources:

1. Answer the card.
2. On the answer screen, tap 📚 Sources.
3. The card's own page opens at its references, with each source and the quote it came from.

For test courses (like citizenship or pilot tests), course pages also link the official sources. Rules change, so check the official source before test day.

Player-made study games are different: the answers come from the study guide itself. Where we could, we checked them against outside sources, and a card tells you if a source agrees or says something different.
