The qualification round is the first stage and consists of five math problems: A, B, C, D, and E. These math problems vary in topic, difficulty, and subject. The problems range from geometry to number theory to make sure that everyone finds interesting problems to work out.

The problems will not only sharpen your mind but also challenge your math skills! All participants of the qualification round will receive participation certificates. You need to solve at least three problems (under 18 years) or four problems (over 18 years) correctly to qualify for the pre-final round.

Participants that have solved the qualification round successfully are qualified to participate in the pre-final round. The problems will be more challenging, but even more interesting!

Problems and Points
The pre-final round consists of 10 problems that vary in difficulty, points, and topic. All topics from geometry to number theory are included. There are three types of problems that give you two, four, and eight points:

    • 4x Basic Problems: The pre-final round includes four basic problems (lowest difficulty). A correct solution to a basic problem adds three points to the total score.


    • 4x Advanced Problems: The pre-final round includes four advanced problems that are more difficult. A correct solution to an advanced problem gives four points.


  • 2x Special-Creativity Problems: The pre-final round includes two special-creativity problems: These problems do not necessary have a final answer, but the approaches and interim results give between zero to six points. This problem type represents real examples of mathematical research and requires special originality and creativity.

It is possible to reach up to 40 points in total. Students have to reach at least 20 points (under 18 years) or 28 (over 18 years) to qualify for the final round.

Participants that have solved the pre-final round successfully are qualified to participate in the final round: a multiple-choice online exam for which students have 60 minutes time.

Exam and Points
The final round consists of a single exam with 40 multiple-choice questions involving mathematical calculations and knowledge. The questions require math skills as well as knowledge about mathematical definitions. Finalists have 60 seconds for each question! To every question there are four possible answers given (only one is correct). A correct answer equals one point. The awards and prizes are given to the finalists with the most points in the final round.

Teacher Registration
The exam will take place in the school of each finalist supervised by a teacher. All finalists have to select a teacher who agrees to supervise the final exam. We will send all required information to the selected teacher who has time to conduct the 40 minutes exam between Monday 7. December and Wednesday 9. December 2020. 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.

Competition Details :

The International Youth Math Challenge is an international mathematics competition that enables students from all countries to prove their math skills and to unleash their creativity.

  • The solution file may be typed digitally or it may be a clear picture of your handwritten notes. Digitally typed solutions receive a special honorary note on the certificates!
  • You can upload one single file! If you have multiple pictures, please compress them into one single file (e.g. you can use ImgToPDF).
  • You can upload PDF and image (jpg, jpeg, png) files. We do not accept any other formats (e.g. ZIP or Word files)! You can use this tool to convert your file into PDF: PDF-Converter
  • The file size has to be below 10 MB otherwise it will be rejected.
  • Important: Make sure that you write your name and birth correctly. It will be used for all certificates!

After you have submitted your solution via the submission form, you can log into your status page. This status page allows you to ...

  • check your status and to check your uploaded solutions.
  • view your results and performance reports of each round.
  • download/access all your certificates.
  • upload solutions for the pre-final round.
  • view your personal information and more.

Important Note: Emails do not always arrive properly (e.g. spam folder). Always check your status page in all rounds. We will post your results, certificates, and important information via your status page!

Eligibility Criteria :
