Student Eligibility

• Students must be in grade 8 or below to be eligible for BmMT.
• Students do not have to be local to the California Bay Area or the U.S. to participate in BmMT. Please see “Satellites” for other options on tournaments.
• Coaches may register multiple teams. We ask that for every 2 teams, there is at least 1 parent chaperone.
• Due to room constraints, we will cut-off registration at 800 students on a first-come, first-serve basis.

Team Finder

Students may register as a team of 1, however, it is beneficial to compete on a team of at least 3 due to our scoring guidelines. For students who do not have a full team, we organized a Team-Finder document. Follow all outlined steps in the document.

BmMT Rounds

Puzzle Round (75 mins)

The puzzle round is a team-based round that consists of a variety of mathematical challenges designed to promote inductive reasoning and lateral thinking.

Individual Round (60 mins)

The individual round consists of 20 short answer questions spanning various subjects typically found in math competitions. This includes, but is not limited to, algebra, geometry, counting, probability, and number theory.

Team Round (60 mins)

The team round consists of 20 short answer questions. Students may work with their teams on these questions.

Relay Round (40 mins)

The relay round consists of 20 problems across various subjects in math. The key feature of this round is that some questions may depend on answers from one or multiple prior questions.

Tiebreakers

Tiebreakers shall only be to break ties for awards, not for honorable mention or distinguished honorable mention.

For non-puzzle rounds:

• Questions are ordered from hardest to easiest based on the number of people who answered correctly.
• Whoever solved the hardest problem among those tied is placed the highest, followed by the one who solved the next hardest, etc.

Puzzle:

• Puzzles are ordered by difficulty based on the average score of all teams on each puzzle.

• Teams are then compared on the total score of the hardest 1/3 of problems.

• If teams are still tied, they are compared on the score of the hardest puzzle, followed by the second hardest, etc.

• If teams are still tied, we go through the following:
  Combined score of the middle third of puzzles
  Individual scores of the middle third of puzzles
  Individual scores of the easiest puzzles.

• For example, the splits for puzzles would look like this:
  8 puzzle problems = 3 hardest / 2 middle / 3 easiest
  10 puzzle problems = 3 hard / 4 mid / 3 easy
  12 puzzle problems = 4 hard / 4 mid / 4 easy

If students are still tied, we will run a tiebreaker round. If teams are still tied, the tie will stand. Tiebreaker qualifiers will be announced at the end of the Relay Round, and will be a 15-minute test. The test will consist of three questions, and be scored primarily on correctness and secondarily on submission time; that is, an earlier submission will be worth more than a later one with the same number of correct answers, but less than a later one with more correct answers.

Acceptable Answers

Students are responsible for familiarizing themselves with the acceptable test formatting document and common notation document for details on how their answers should be submitted. Answers not submitted in the listed formats will be graded as incorrect, even if equivalent.

Scoring

To calculate the individual score, we will take the average of every team member’s score on their individual portion if the team has 3, 4, or 5 members. If the team has fewer than that many members, we will add 0’s until the team has reached at least 3 scores, of which we will take the average.

While individuals are allowed to register a 1-person team, we highly encourage students without a team to use the Team-Finder to create a team of at least 3.

Scores for a given round will be normalized by either the top 10 scores or the top 10% score, whichever is greater.

The event will run from 8:00 AM to 6:30 PM.

Frequently Asked Questions

Are calculators or other reference material allowed?

Graph paper and calculators are prohibited, but protractors, rulers, and compasses are permitted. Blank white scratch paper will be provided for all participants. All answers must be exact, reduced, and simplified. Illegible answers will not be graded. Cheating in any form will not be tolerated, and failure to comply with all rules may result in immediate and irreversible disqualification.

Can elementary school students compete? What if I don’t have a team?

Yes! BmMT is open to any student in 8th grade or below, including those who haven’t entered middle school. While students are allowed to compete as individuals under “LAST_NAME Homeschool” or some other variation, we highly recommend that students compete on a team of at least 3 due to our scoring guidelines. To calculate the overall Individual score, we will take the average of every team member’s score on their individual portion if the team has 3, 4, or 5 members. If the team has less than that many members, we will add 0’s until the team has reached at least 3 scores, of which we will take the average.

How are awards handled?

Awards will be physically presented to contestants at BmMT 2024’s closing ceremony.

I’m in a different timezone or non-local and can’t compete live. What are my options?

There will be BmMT Satellite competitions held through our partners across the globe for competitors wishing to compete in a different time zone.

Will lunch be provided?

Lunch is not provided for BmMT 2024. Students, coaches and parents are free to find food in Berkeley. Restaurants can be found on the south side of campus (~5 minute walk from home rooms) and downtown (~15 minute walk from home rooms).

Where can I find parking / How can I get around Berkeley?

BmMT will not be providing parking or travel arrangements for students — it is up to coaches and/or parents to handle travel logistics. There are a number of parking garages around the campus, including Underhill Structure, Lower Hearst Structure, and the RSF garage. In addition, UC Berkeley campus is very public transport friendly. If you are staying in Emeryville, Bus Line 36 will take you directly to campus, and the Downtown Berkeley BART station is next to campus.
