1. Qualification Round

The Qualification Round is the first stage and consists of five math problems (A to E). The problems encompass a wide range of topics, varying in difficulty and discipline. They range from geometry to number theory to make sure that everyone finds interesting problems to work out!

The problems will test your math and problem-solving skills. All participants of the Qualification Round will receive participation certificates. Each problem gives 5 points and you need to score at least 15/17/20 points (Junior/Youth/Senior, see age groups ) to qualify for the Pre-Final Round.
Submission Information
In order to avoid connection issues, upload errors, and other problems, please submit your solution before the official submission deadline (22 December 2024). The solution file may be typed digitally (recommended; e.g., TeX), or it may be a clear picture of your handwritten notes. In case you have multiple pictures, you may use an online tool to combine the pictures into a single PDF file. Make sure that you write your name, school, city and date of birth correctly! The details will be used for all certificates. There are no fees or registration costs to participate in the Qualification Round.
Announcement of Results
You will receive an email about the results; however, you can also check your participant account for your results, performance report, and certificates online. Please log into your participant account so as not to miss any critical information: Login for Participants

2. Pre-Final Round

Participants who solved the Qualification Round successfully are qualified to participate in the Pre-Final Round. The problems will be more challenging but also more engaging!

Problems and Points
The Pre-Final Round consists of six problems that vary in difficulty, points, and subject. All topics from geometry to number theory are included, as well as real-world research material. There are three types of problems that give you four, six, and eight points:

• 2x Basic Problems (4 Points)
  The Pre-Final Round includes two basic problems (lower difficulty).


• 2x Advanced Problems (6 Points)
  The pre-final round includes two advanced problems (higher difficulty).


• 2x Special-Creativity Problems (8 Points)
  The Pre-Final Round includes two special-creativity problems whose experimental format varies each year. Usually, one of them presents a real-world example of mathematical research or requires particular originality.

It is possible to reach up to 36 points in total. Participants need to score at least 16/20/24 points (Junior/Youth/Senior, see age groups ) to qualify for the Final Round.

Process and Submission
All participants who are qualified and registered for the Pre-Final Round will receive the problems via email or via their participant account on Thursday, 23 January 2025. From that day on, you have four days until Sunday, 26 January 2025 to solve as many problems as possible. You can submit your solution online via a dedicated submission form. You can choose if you would like to submit the solution as a handwritten version or as a digitally typed document. We recommend writing the solution in the blank space on the problem sheets of the Pre-Final Round. Please highlight your final solutions.

Registration and Costs
If you succeed in the Qualification Round, you can choose to participate in the Pre-Final Round by registering from your participant account. This educational opportunity comes with diverse costs, including those for human resources, technical infrastructure, materials and more. While our sponsors cover some of these expenses, we need to ask participants to cover this year's Pre-Final Round registration costs of 11 EUR to make IYMC on an international level possible. The registration costs are necessary to provide the resources required to run a competition at this scale, including evaluation, in particular, for the comprehensive Pre-Final Round. There are no other costs involved. You can find detailed information about the registration costs here: Registration Costs Flyer [PDF]

3. Final Round

Participants who have solved the Pre-Final Round successfully are qualified to participate in the Final Round: a multiple-choice online exam with 20 questions.

Exam and Points
The Final Round consists of a single exam with 20 multiple-choice questions involving mathematical calculations, logic and knowledge, in particular related to the Qualification and Pre-Final Round. Finalists have 60 seconds for each question. There are four possible answers to every question (only one is correct). A correct answer equals one point. There are no negative points for incorrect answers. The awards and prizes are given to the finalists with the most points in the Final Round. If multiple participants have the same score, the points from the Pre-Final Round (and Qualification Round) are used to determine the final winners.

Teacher Supervision / Self-Recording
Finalists take the exam via a dedicated online exam portal (iymc.info/exam). The online exam is conducted in the participant's school, where a teacher supervises each finalist. All finalists have to select a teacher who agrees to supervise the exam. We will send all required information to the selected teacher who has time to conduct the 20-minute exam on Tuesday, 18 February 2025. The teacher has to make sure that the finalist does not cheat and does not open any other browser tabs, websites, programs, or computer windows during the exam. Participants can also record their exams with a video camera or smartphone and upload the video. In this case, no teacher is needed.
