Overview
The Iberoamerican Mathematical Olympiad (OIM, Olimpiada Iberoamericana de Matematica) is held every year for students from Iberoamerican countries. The first edition was in Paipa, Colombia, in 1985. The details below follow the regulations published by the host of the 2013 edition, so check that they are still current.
Who can take part
Students must not have turned 18 by 31 December of the year before the Olympiad.
A student cannot have taken part in two earlier Iberoamerican Olympiads.
Each invited country may send a team of up to four students, a head of delegation and a tutor.
Participants are chosen by their country's national mathematical olympiad or selection process.
Exam pattern
| Item | Detail |
|---|---|
| Papers | Two written papers on two consecutive days, 4.5 hours each |
| Problems | Three per paper, six in total |
| Permitted items | Only writing and drawing instruments |
Each contestant works individually. Books, notebooks, tables and calculators are not allowed. Written questions about the wording of the problems may be asked in the first thirty minutes of each day.
Marking and results
Gold, silver and bronze medals go to about 50 percent of participants, in a ratio of about 1:2:3. Honourable mentions go to students who solved a problem perfectly but did not reach a medal score. Every participant receives a diploma.
How to take part
Entry is through your country's national mathematical olympiad. The national organiser selects the team.
Preparation tips
Practise olympiad-style proof problems in geometry, number theory, algebra and combinatorics.
Use past OIM papers, which host countries and national olympiads publish.
Note
Confirm team size, dates and host with your national olympiad for the current year.
