Format & Scoring

• A student may leave to use the restroom during the exam, but they must turn in their phone to a proctor to do so.

• No computational aids other than a writing utensil are allowed.

• If a student is caught cheating on an individual round, they will get a -X for that round.

  • Where X is the score of the highest scoring individual on that round

• If a student is caught cheating on a team-based round, their team will get a -X for that round.

  • Where X is the score of the highest scoring team on that round

• If a proctor has reasonable suspicion to believe that a student is cheating, the proctor reserves the right to declare cheating.

• Grading decisions (including TCS) can not be protested, but answer protests are welcome in the #protests-disputes channel on discord.

This is a 60 minute test with 2-3 problems to be completed as a team. Each question is worth the same number of points.

•     Communication within the team is permitted.

•     Solutions should be written in english.

Solution format:

•     Number all of the pages of the solution.

•     The bound that is attempted to be proven must be stated clearly before each proof.

•     You may only submit one bound per problem.

This is a 40 minute test with 10 problems to be completed as a team. Each question is worth the same number of points.

•     Communication within the team is permitted.

•     Answers must be reasonably simplified.

There are three different rounds: Algebra and Number Theory, Combinatorics and Computer Science, and Geometry. Each student will take all 3 exams.

Each round has 10 problems (and a tiebreaker) which need to be solved in 50 minutes. Note that harder/less-solved questions are worth more points

During the round NO communication with anyone will be allowed.

Scoring

• The tiebreaker question will ONLY be used as a tiebreaker. It will not actually add any points to your score.

• Ties among people with the same score will be broken as follows:

  • People who submitted ANY answer to a tiebreaker will automatically win ties over those who did not submit an answer

  • For those who submitted a tiebreaker answer, whoever is closer to the correct answer will win the tie

  • Among students who submitted the same tiebreaker answer (possibly blank), CMIMC will use any arbitrary tiebreaking method chosen that day.

Individual

• Individual rankings will simply be done by summing the student's individual scores across all 3 rounds.

• Ties will be broken using the same procedure as described above

Team

• Team rankings will be calculated by weighing and summing the scores on the TCS, team, and each student's individual score
