* The power round is worth about 30% of the overall team score.

### Team Round

*For more information, please visit this page.*

* The team round requires each team to split evenly into two groups and complete relay-style questions, to be completed in 20 minutes.
* There are 10 questions, where each question consists of two parts. The answer to the first part is needed for the second part.
* Each group receives the first part of 5 questions and the second part to the other 5 questions.
* Competitors can only collaborate with team members in their group. They cannot collaborate with team members in the other group.
* The team round is worth about 20% of the overall team score.
* If a team does not take the team round, it is treated as if they received a score of 0 for scoring purposes.

### Individual Rounds

*For more information on general individual round rules, please visit this page.*
*For more information on a specific individual test, please find the test on this page.*

* Each individual round consists of ten-short answer questions to be solved in 60 minutes.
* Each competitor takes two different individual rounds out of the five available: algebra, combinatorics, geometry, number theory, and computer science.
* The individual score consists about 50% of the overall team score.
* A team with fewer than six members will be treated as if extra members received a total score of 0.

### Finals

*For more information, please visit this page.*

* Each individual takes one final round for each subject representing the subject in which they qualified.
* Each final round consists of three-short answer problems to be solved in 20 minutes or less.
* Competitors can submit at any time, but they only submit once. Ties will be broken based off of the number of problems solved, then by submission time.

## Conventions

* Answers to problems do not have to be integers. For more information about acceptable answer submissions, please visit this page.
* Diagrams do not have to be drawn to scale.
* The vertices of a polygon appear in the order by which it is named. So, for example, heptagon ABCDEFG has vertices appearing in that order.

## Awards

* Awards are given to the top ten scoring individuals from each subject, and the top five scoring teams for the power round, team round, and overall.
