The contest is composed of hundreds of short answer problems. The participants compete in teams of up to three members.

The problems cover various topics like counting, summations, optimization, inequalities, series, graphs, logic, geometry and many more.

Problems are split into six categories: algebra, geometry, combinatorics, number theory, international and miscellaneous. Within each category, the problems are approximately sorted by their difficulty, ranging from easy to very hard.

Not all problems are shown at the beginning of the contest. They are instead uncovered throughout the contest. However, all problems will be uncovered in the first half of the contest, that is, until 3 PM.
