Regulations of the Nordic Mathematical Contest
Issued by Finland for the NMC 2010. Minor editing by
Denmark for the NMC 2011. Minor revision at the meeting of the Nordic
leaders at the IMO 2014.
The Nordic Mathematical Contest (NMC) is a
competition organised annually for secondary school students in
Denmark, Finland, Iceland, Norway and Sweden. The competition is
arranged jointly by the organisations of the participating countries
responsible for the selection and training of the national teams for
the International Mathematical Olympiad (IMO). These organisations
will be called national organisations. The primary aims of
the contest are to
- provide the participants with an experience with a mathematical
contest at an international level;
- provide the national organisations with information relevant for
the selection of the IMO team of the country.
The representatives of the national
organisations meet annually at the IMO to set the date of the next NMC
and to discuss matters related to the contest.
Each participating country can enter a maximum
of 20 competitors. The competitors should be eligible to participate
in the IMO of the year of the competition as members of the team of
their country. Also other secondary school students from the
participating countries are allowed to compete. The participants are
chosen by the national organisations. Before the competition each
country sends a list of the names of their contestants to the host.
The names and scores of the approximately best 25 to 30 participants will be posted at the NMC homepage. All names and scores are communicated to every national organisation and every participant.
The arrangement of the competition
Each year, one of the national organisations,
called the host, is responsible for the general
arrangements of the contest. The order is as follows (year mod 5): 0:
Finland, 1: Denmark, 2: Sweden, 3: Norway, 4: Iceland. The national
arrangements in each country are taken care of by the national
The contest takes place in March or April on a
date agreed upon by the participating organisations. The preferred
time of the contest is suggested by the host. The competition problems
should be kept confidential until the day after the contest. In the
contest, the participants solve four problems within four hours. The
only tools allowed are paper and writing and drawing instruments. The
contestants can write in their own language. The problems are marked
on a scale from 0 to 7. Only integers are used.
The mathematical content covered by the
problems is that of the IMO; their intended level of difficulty is
slightly below that of the IMO.
The host prepares the problem paper in English
on the basis of problem proposals submitted by the national
organisations including the host. The national organisations prepare
translations of the problems into the languages of the
participants. The host may review the translations before the
contest. The final problem papers should be ready to be mailed to the
sites where the exam is held well in advance of the date of the
The national organisations are responsible for
the necessary arrangements in their country. The students write the
exam in their own school or at another suitable site. The national
organisations collect the scripts, mark them preliminarily according
to a marking scheme provided by the host, and send them with
sufficient comments and necessary translations to the host. The host
performs the final marking of all the scripts and informs the national
organisations of the results. The decisions of the host are final. The
national organisations are free to publish the results after receiving
them from the host.
The host informs the national organisations on
deadlines for sending in problem suggestions and scripts. The aim is
to have the final results well before the end of the school year. The
host issues a diploma of participation to every participant and
decides on the number of participants whose diploma indicates the rank
of the contestant. No other prizes are given. The national
organisations are responsible for the distribution of the diplomas to
the participants or their schools.
The host can decide on minor deviations from
these rules if necessary.
