About Caribou

The Caribou Mathematics Competition is a world wide online contest that is held six times throughout the school year. Each of these days, five contests are offered, one for each of the grade levels 3/4, 5/6, 7/8, 9/10 and 11/12 and each one in English, French and Persian.

The Caribou Cup is the series of all Caribou Contests in one school year. Each student's ranking in the Caribou Cup is determined by their performance in their best 5 of 6 contests through the school year.

All of our previous contests are available for free online as previous tests.
