Traditionally every participating university sends several students and one or more Team Leaders. Individual students and teams of students, with or without a Team Leader, that do not represent any university are also welcome. Each Team Leader is expected to hold an academic position in some university level institution and participate in the marking of the work of all participants.
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 some exceptions can be made. There is no minimum age limit. Problems are from the fields of Algebra, Analysis (Real
and Complex), Geometry and Combinatorics. The working language is
This is a residential competition and a condition of participation is that all participating students stay in the Hall of Residence provided by the organisers. Over the past twenty seven competitions we have had participants from over two hundred institutions from over fifty countries.
Selection of the Problems The
problems are chosen at the Meeting of the Jury from those received
in advance by the President of the Jury, Professor John Jayne.
Evaluation The students' work is
evaluated by Team Leaders and other Professors and Assistant
Professors using criteria provided by the Jury.
Groups 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. This year students from Russia can only participate as individuals, unaffiliated and unattached to any university; and they will not be included in any teams.
Warning. The on-line exam times has been modified.
In-person, Balgoevgrad: 9:00 - 13:00, Sofia time (UTC+3)

The contest problems will be selected by the
in-person members of the International Jury, on the jury
meeting on 2 August.
The two contest days are 3 and 4 August.
On each day, there will be 4 problems for 4
hours each day. The students must write their solutions on A4
or US letter papers. Only the standard drawing tools (pens,
straightedges etc.) and printed dictionaries are
allowed. Using any electronic tool or printed material is not
allowed. The scripts should not contain any text, name or mark
from which the student can be identified. The language of the
contest is English; solutions written in other languages will
not be evaluated.
Both contest days, there will be three exams.
In person competitors have the exam at the AUBG campus,
in Blagoevgrad, from 8:30 to 13:00 Sofia time; the exam
starts at 9:00.
On-line students and teams from Europe, Asia and Africa
must take the exam between 6:00am and 10:00am UTC (same as
the in-person exam).
On-line students and teams from America must take the
exam between 1:00pm and 5:00pm UTC.
All members of each team should start at the same time, with
downloading and printing the problems.
Opening and Closing Ceremony
The Opening and Closing Ceremonies will be
held in Blagoevgrad. We plan to record the ceremonies, and share
them with 2 hours later at the IMC's YouTube channel.
We will organize two Virtual Contest Halls
for teamless students.
In the EurAsian Hall we will start the
contest at 6:00 UTC and finish at 10:00 UTC. For
example, this is 13:00 to 17:00 in Hanoi and Novosibirsk
and 12:00 to 16:00 in Bangladesh.
In the American Hall we start at 13:00
UTC and finish at 17:00 UTC. This is 8:00 to 12:00
in Mexico City and 10:00 to 14:00 in Rio de
The links to the Contest Halls will be
sent by e-mail.
The Team Leaders
have to organize the invigilation of all their students
and ensure that their work is fair. Students who are not
invigilated will be removed from the
If personal invigilation is not possible,
the team leader watches the students by video calls like Zoom,
Google Meet, Skype etc. In that case the students have to set
up a webcamera that captures the place. The video must show
the student and his desk. No computer screen is allowed in
front of the students and the students should not wear ear-
and headphones. (See the pictures below.)
If you are a teamless student, you have to set up a webcamera
yourself that captures you and your desk. It is allowed to use
only one camera if there are more students in the same room. By
15 minutes before start, you have to connect the video, download
and print the problems. The video link will be sent you by
Preparing and uploading solutions
At the end of the exam, each student has to produce
5 files, containing the solutions:
The scripts must be uploaded as soon as
possible after the 4 work hours has passed.
For creating the files it is recommended to use the application named
CamScanner, available both for
Apple based cell phones. Using
CamScanner it is easy to make photographs of the papers,
crop, resize and rearrange the pages and save the pictures
into a PDF. If your phone has internet connection, you can
upload the files immediately.
Each student will receive his personal
upload link. Please use only your own link.
For a demonstration, we made a short
it to see how to use CamScanner. Test different camera
settings; perhaps it is better if flash is switched on.
All leaders are expected to participate in
grading. We created a project at ZulipChat for the grading
discussion. All Team Leaders will be invited there. Further
information for Team Leaders will be posted in ZulipChat.
In-person participants should pay the
registration fee at the IMC site at AUBG in Blagoevgrad when
particpants, the deadline for paying the registration fee
has exprired. All on-line students who did not pay, and
all leaders who are not leaders or deputy leaders of a
team, will be deleted.
