International Mathematical Olympiad

The International Mathematical Olympiad is the pinnacle of all high school mathematics competitions and the oldest of all international scientific competitions. Each year, countries from around the world send a team of 6 students to compete in a grueling competition.

Format of the Competition

The competition takes place over 2 consecutive days. Each day 3 problems are given to the students to work on for 4.5 hours. Following the general format of high school competitions, it does not require calculus or related topics, though proofs using higher mathematics are accepted.

Scoring

Scoring on each problem is done on a 0-7 scale (inclusive and integers only). Full credit is only given for complete, correct solutions. Each solution is intended to be in the form of a mathematical proof. Since there are 6 problems, a perfect score is 42 points.

Awards

Medals and honorable mentions are given out. Sometimes, other prizes and awards are given to contestants too.

  • Gold - the top 1/12 of individual scores.
  • Silver - the next 2/12 of individual scores.
  • Bronze - the next 3/12 of individual scores.
  • Honorable mention - any student who receives a score of 7 on any one problem but did not receive a medal.
  • Special Prize - Given to students who score 7 in one problem with an especially insightful solution.

Team Competition

There is no official team competition. Unofficially, however, the scores of each team are compared each year where a team's score is the sum of their individual scores.

History

The IMO started in 1959 as a competition among Eastern European countries. Since then, it has evolved into the premier international competition in mathematics.

Problem Selection

Each year nearly every country proposes several problems in consideration for the International Mathematical Olympiad. All submissions are compiled into a Longlist, the length of which can easily exceed 100 problems. Then the IMO deputy leaders convene on site and discuss which problems should be used on the International Mathematical Olympiad test that year. Eventually most of the problems on the Longlist are eliminated from consideration, and what is left is a shortlist, with a length between 26 problems and 32 problems, spread out across the topics of Algebra, Combinatorics, Geometry, and Number Theory. The six problems are then chosen out of these.
