# Math Contest Rules

## General Rules

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.

## TCS (Theoretical Computer Science) Round

This is a 60 minute test with 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.

## Team Round

This is a 60 minute test with 15 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.

## Individual Rounds

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 60 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.

## Overall Rankings

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
