Olympiads are also a good way to hone your analytical skills and sharpen your problem-solving skills.
We’ve covered the program in detail below, with all the information you need to prepare for the olympiad.
What is the International Math Olympiad (IMO)?
The International Math Olympiad (IMO) is one of the top international mathematics competitions for high school students, running ever year since its first edition in Romania in 1959. The competition brings together the national champions from over 100 countries at the final event, that’s held in a different country every year. The competition runs for roughly 10 days, covering all formalities. Participants will be engaged in contests for two days, answering three questions every day.
The competition invites teams of up to six high school contestants (aged 14-18) to appear for two exams on consecutive days. Each exam lasts 4.5 hours, containing three problems each. Contestants are awarded Gold, Silver, and Bronze medals, as well as Honourable Mentions for outstanding effort.
Over 600 competitors from more than 110 countries are expected to participate in the 65th edition of the International Mathematical Olympiad (IMO), which will take place at the University of Bath in July 2024.
How is the IMO structured?
Only national champions from participating countries are eligible to participate in the international competition. To participate in the international olympiad, you need to be a high school student and your name should be submitted by the participating organization from your country. For example, if you are a high school student in the USA, you need to first participate in the American Mathematics Competitions, which are organized by the Mathematical Association of America.
If you clear the initial rounds, AMC 10/12 (10 & 12 refer to the grades of the students) you are invited to the American Invitational Mathematics Examination (AIME) which is the qualifying round for the USA Mathematical Olympiad (USAMO). Top performers at the USAMO are invited to the Mathematical Olympiad Program (MOP) and top performers are invited to represent the United States at the IMO.
What is the syllabus for the IMO?
The IMO consists of two exam days, where each exam is 4.5 hours long and consists of three complex problems.
The difficulty level of problems is consistent every year. Participants will attempt to solve problems featuring algebra, precalculus, complex geometry, functional equations, combinatorics, and number theory. Technically, you won’t need to be experienced in calculus or have knowledge of advanced university-level mathematics to solve these problems, however, knowing the basic fundamentals of these concepts will definitely be an advantage. While there is no defined syllabus or curriculum for the competition, problems will cover these main categories – algebra, combinatorics, geometry, and number theory. The problems will test your problem-solving skills to the max.
All students are expected to be fluent in mathematical proofs as this competition asks students to solve proof-based questions or determine values by solving equations in a step-by-step manner. You will benefit from having a solid command of topics in algebra, geometry, number theory, combinatorics, and probability. Topics like induction and proof by contradiction are also considered important for the competition.

Scoring & Prizes:
Each of the 6 problems (2 exams with 3 problems each) is worth 7 points. Based on your performance, you may be awarded Gold, Silver, or Bronze medals. The point criteria change every year, but IMO tries to set it such that roughly 50% or fewer participants win a medal, with gold, silver, and bronze winners in a 1:2:3 ratio.
Aside from these medals, you could also win an Honorable Mention for a strong answer. While all scores are awarded to individual participants, the team scoring is taken into consideration to judge which participating country will be the overall winner.
10 tips to help you ace the IMO:
Carefully study problems from past editions: The IMO provides a collection of previous years' problems that you can solve. This will help you get a sense of the competition's difficulty level. By studying past problems, you’ll find out which areas are your strengths and which areas you need to work on. For detailed problems and solutions, you can refer to this link.
Practice regularly and start preparing well in advance: To score well, there’s really no other alternative to a detailed preparation schedule, which you need to stick to religiously.
Find a mentor/guide: While you don’t need to know college-level math to solve IMO problems, what you do need is a good teacher or mentor who will guide and coach you on the foundational knowledge and problem-solving techniques required. This could be your math teacher, but it could also be a specialized coach or university professor who is interested.
Sign up for math clubs: Math clubs are a great way to interact with like-minded peers who might also be interested in competing in the IMO. Not only that, when you interact with other students, you stand to gain useful tips like shortcuts and mental math tricks that they might be aware of.
Join an online forum: Online forums are very useful if you find yourself stuck with problems or just want to discuss any topic of interest in a particular field. There are forums dedicated to Olympiad problems, which can help you prepare.
Visit the IMO site regularly to check for updated resources: The IMO provides the questions from previous editions on the website, and links to resources that you can use while preparing. Register for resources like Art of Problem Solving or Mathlinks, as they are updated regularly and also provide detailed solutions to past IMO questions.
Practice time management: One of the toughest aspects of the IMO is the limited time you will have to solve incredibly complex questions – you effectively have only an hour and a half per question. You’ll need to learn to manage your time efficiently, making sure you to focus on one question at a time with time limits in mind for each.
Enroll for an Olympiad training program, organized preferably by a former Olympiad participant: There are several programs available online, which can boost your preparation for the IMO. Most of these programs will help enhance your problem-solving skills and work on reducing the time you need to solve complex problems. Some programs like this also include a mock-test feature as well, which will be highly useful as the competition date nears.
Ensure consistent preparation efforts and set realistic goals: Placing in the IMO is determined by your hard work over a long period and there are no shortcuts. It is as much a test of your endurance and resilience as it is a test of mathematics. Try to maintain a positive attitude and stay calm and focused to give yourself the best chance.
Prepare quick notes for revision: As the IMO has four major subject categories that the questions will cover, you can create brief notes and shorthands of formulae for each topic to help you revise quicker. These notes will be very useful for future references and revisions, hence helping you learn faster.
