What are the ABMC Online Contests?

The ABMC Online Contests consists of 3 rounds of tests (1 round per month), each containing 10 questions.

Students will have a total of 38 hours before the submission deadline to work on their own schedule.

All ABMC Online Contests will be done individually.

When a contest begins, problems and the submission form will be posted on this page. The answer submission form will ask for name, grade, school, and email, so no preregistration is needed.

Participation is free.

When do these contests take place?

The anticipated dates are as follows:

  • October: Saturday, October 19th – Sunday, October 20th
  • November: Saturday, November 16th – Sunday, November 17th
  • December: Friday, December 20th – Sunday, December 22nd

Each set will be released at 8:00 AM the first day, and submissions close at 10:00 PM on the last. No late submissions will be permissible.

You may take as long as you require, so long as you submit before the deadline.

Rules

No calculators, online resources,  and other computational resources are admissible.

Drawing aids, such as rulers and protractors are permissible, however, software such as GeoGebra is prohibited.

All answers are non-negative integers between 0 and 100,000.

Grading and tie-breaking

Each problem is worth 1 point.

Ties will be broken by the ‘most difficult’ problem solved. If problem A was solved by contestants, and problem B was solved by b contestants, with a < b, then A is more difficult than B.

For prizes and total scores, only a contestant’s two highest scores will be considered.

Will prizes be awarded?

In each grade, contestants who perform within the Top 5 within each round will have their names posted on our website. Additionally, contestants who perform within the Top 15 over all 3 contests will have their scores posted.

Top scorers of each grade will also be displayed.

Physical prizes (such as AoPS gift certificates, merchandise, calculators, etc.) will be given to top scorers if they attend the ABMC onsite contest.
