The IMO Olympiad (International Mathematics Olympiad) is a yearly school level Mathematics Olympiad exam conducted by the Science Olympiad Foundation (SOF) for students from Class 1 to Class 12. It assesses the mathematical thinking, problem-solving and logical thinking abilities of children outside the school curriculum and the highest achievers receive international, zonal and school level certificates, medals and cash prizes.
The IMO exam can be a great way to give your child confidence in maths if they like numbers, puzzles and problem solving. This is a basic, parent-friendly reference to all you need to know.
What is the International Mathematics Olympiad (IMO)?
The International Mathematics Olympiad (IMO) is a school-level mathematics competition organized by the Science Olympiad Foundation (SOF) which is one of the largest and most prestigious mathematics competitions in the world. It is open to students from Classes 1 to 12, and is held every year in thousands of schools in India and globally.
One common misconception that must be addressed is that there is also an existing older "International Mathematical Olympiad" which is a competition for the best high school students from various countries based on proofs. It's another test altogether. This guide is in relation to the SOF IMO, which is the school level Olympiad which most Indian students and parents are referring to when they ask about the "IMO exam.
SOF IMO is not only a test of School Maths, it is also a test of Mathematical reasoning, Logical thinking and using concepts in higher order and real world problem situations.
IMO Eligibility Criteria
The eligibility criteria of IMO are similar to other SOF Olympiads and are very simple and inclusive.
|
Level |
Who Can Appear |
Eligibility Rule |
|---|---|---|
|
Level 1 |
Classes 1–12 |
Students from classes 1–12, enrolled in a school recognized by SOF, are eligible |
|
Level 2 |
Classes 3–12 |
Only students from classes 3–12 are eligible; class-wise top 5% of Level 1 participants are selected |
No student is barred from taking part in Level 1: there is no minimum marks requirement. A student must satisfy one of the following for Level 2:
-
Top 5% of candidates (class-wise) based on their performance at the international level in SOF IMO Level 1.
-
The top 25 of the ranked players from each Zone and Category.
Only Classes 3-12 will have a Level 2; Classes 1 and 2 will have only a Level 1.
IMO Exam Pattern
The IMO exam is a simple MCQ based exam and similar to the other SOF Olympiads, there is no negative marking, which means that kids can attempt all the questions without any hesitation.

The exam is broken up into four parts: Logical Reasoning, Mathematical Reasoning, Everyday Mathematics, and the Achievers Section. The pattern is a little different for the senior classes, e.g., in Classes 11 and 12 there are 25 questions in Mathematics, 20 questions in Mathematical Reasoning or Applied Mathematics and 5 questions in the Achievers Section. The Achievers Section is weighted, with Achievers questions being worth 2 marks each in Classes 1-4 and 3 marks each from Class 5 onwards — often the final ranks are decided in this section.
The exam has two stages:
-
Level 1 – School-level round (open to all registered students).
-
Level 2 – Only Classes 3-12 compete in a Level 2 round which is for those who qualify from Level 1.
IMO Syllabus (Class-wise Overview)
T The glad news for parents: Children don't require any separate textbook for IMO preparation. The difficulty level is gradually rising from Class 1 to Class 12 and SOF IMO syllabus is based upon the curriculum of CBSE, ICSE/ISC, and State Boards.
60% of the questions are based on the current class syllabus and 40% of the questions are based on the previous class syllabus, so a quick revision of the basics of last year is really helpful.
|
Class Group |
Main Focus Areas |
|---|---|
|
Classes 1–2 |
Patterns, number sense, geometrical shapes, spatial understanding, basic reasoning |
|
Classes 3–5 |
Number operations, measurement, fractions, geometry, data handling, reasoning puzzles |
|
Classes 6–8 |
Algebra basics, ratio-proportion, mensuration, data handling, logical reasoning |
|
Classes 9–10 |
Real numbers, polynomials, linear equations, quadratic equations, triangles, coordinate geometry, trigonometry, circles, statistics, probability |
|
Classes 11–12 |
Advanced algebra, calculus basics, applied mathematics, mathematical reasoning |
The syllabus information changes every year in SOF so it is better to download the latest official class-wise PDF from the SOF website before preparing.
IMO Exam Dates and Registration Process
Similar to the NSO, IMO registration is only done by schools, and not by individual students.
-
Schools select one of the official exam dates provided by SOF (Level 1).
-
School's Olympiad Coordinator takes the student information and registration fee.
-
Students are encouraged to prepare the IMO syllabus for Level 1 for the exam with good marks.
-
Normally the results are available about 6 weeks after the final leg of the exam, and Level 2 results about a month or two later.
The exact dates may change slightly each year so please refer to your school or the official SOF website nearer to the exam season.
IMO Preparation Tips for Parents and Kids
A little practice is better than much cramming. Here are some easy IMO preparation tips:
-
Be familiar with the syllabus. Review the class-wise topics to ensure that your child is learning the appropriate topics.
-
Solve previous year papers. This helps to get used to the style and timing of questions.
-
Practice reading and writing quickly and correctly. Timed mock tests are a great help as there is only 60 minutes for as many as 50 questions.
-
Get the children to develop their reasoning powers, not just their calculation powers — many of the questions in IMO test what a child knows and not how he or she thinks.
-
Use structured practice books. Well-structured Olympiad books such as those by Oswaal Books provide parents with chapter-wise practice sets and previous year papers which help them to guide revision at home.
-
Maintain a positive tone. Think of it as a game instead of a test.

Summary
The IMO Olympiad (SOF International Mathematics Olympiad) is a school level Mathematics competition for Classes 1 to 12 organized by the Science Olympiad Foundation. It consists of two levels, no negative marking and a syllabus based on regular CBSE/ICSE/State board curriculum with an emphasis on logical reasoning and higher order thinking. Registration is only through schools and the top performers at Level 1 progress to Level 2 for national and international recognition. By preparing well, children can face the IMO exam with curiosity and confidence, not under pressure, with proper understanding of the syllabus, solving past papers and utilizing structured resources such as Oswaal Books.
