IMC will be ON-LINE

We were hoping that IMC could return to American University in Bulgaria in Blagoevgrad and it could be held in the traditional way. But, due to the uncertaninity in the pandemic situation and the various travel restrictions and quarantine regulations, the Organizers decided to hold the upcoming IMC on-line.

We hope that we can meet in person next year so that next year's competition in 2022 will a residential competition and a condition of participation is that all participating students stay in the Hall of Residence provided by the organisers.

Those who registered before 15 May, have to register again.


Every participating university enters several Students and one or more Team Leaders. Individual students without a Team Leader are welcome.

The competition is planned for students completing their first, second, third or fourth year of university education with a maximum age of participants being 23 years of age at the time of the competition, although exceptions can be made. There is no minimum age limit.

Each Team Leader is expected to hold an academic position in a Faculty of the Institution that they represent. The Team Leaders have to organize invigilating the students' work and ensure that their work is fair.

All Team Leaders are expected to participate in evaluating the student's scripts.

Subjects of the contest

Problems are from the fields of Algebra, Analysis (Real and Complex), Geometry and Combinatorics. The working language is English.

Selection of the Problems

The problems are chosen by the International Problem Selection Committee from those received in advance by the President of the Jury, Professor John Jayne.


The students' work is evaluated by Team Leaders and other Professors and Assistant Professors using criteria provided by the Jury.

Teams Contest

Although this is an individual event, the Universities traditionally divide their participants into groups of four each. The number of students in the teams is, however, not fixed. Each Team's result will be computed as the sum of the three best students and the average of the team.

IMC Ethics Committee

The Ethics Committee watches and guides he participants and help them keep fair and honest. The chairman of the Committee is Ivan the Confessor.


Please don't leave registration to the last moment. Each student has to enter his Team Leader, in order to declare that they belong to that team. The Team Leader also has to enter their team members' e-mail addresses. In both cases, the address must be typed precisely. We have seen several difficulties caused by using multiple e-mail addresses, mixing lower and upper case letters or putting spaces in e-mail addresses. We try to correct errors. If you have any difficulty, please contact the organizers.

The registration fee is 25 GBP (British Pounds) for students who belong to a team, so both the student and their team leader must declare that the student belongs to the team. In all other cases the student is considered "teamless" and their fee is 50 GBP (British Pounds). There is no fee for Team Leaders.

The deadline for paying the registration fee is 30 July. From 31 July, registration will be closed and all students who did not pay, and all leaders who are not leaders or deputy leaders of a team, will be deleted.
