A school with less than 300 students enrolled in grades 9-12 may enter from one to six contestants in each division. Schools with more than 300 students enrolled in grades 9-12 may enter from one to 10 contestants in each division. If your school has less than 300 students but you wish to enter more than 6 students in any category, your school will be classified in the A division.    


The contest will consist of a fifty-minute test followed by a twenty-minute test. The latter will be scored only if it is necessary to break ties. The contestant's score will be the score achieved on the fifty-minute test.

Pencils and Paper

All contestants should plan to provide their own pencils. The college will provide scratch paper.

Tests and Scoring

The tests in all divisions will be prepared and scored by the faculty of the Mathematics Department at South Dakota Mines.

Calculators and Cellphones

Calculators are not necessary for the exam and we will not allow their use. The use of cellphones is strictly prohibited during testing.


Schools will be split into two classes: Class A and Class B. Please indicate your school’s enrollment in grades 9-12 and we will classify you accordingly. Prizes will be awarded in each class to the top five in each division. The top scorer in each division will be awarded a prize. The exception is in the Master's Division, which will have only 1 prize, to be awarded to the top scorer.
