How the content is made
The lessons, guides and practice tools are written and maintained by the people behind CardCount Academy. Counting values, examples and calculations are checked against the code that powers the drills and quizzes, and the practice logic is covered by automated tests. Where a guide makes a factual claim, it lists its sources. Each guide shows the date it was last reviewed.
