What is the International Mathematics Olympiad (IMO)?

The International Mathematics Olympiad (IMO), conducted by SOF, is designed to test students' mathematical reasoning, analytical skills, and problem-solving abilities. The Olympiad is conducted at both national and international levels and includes students from Class 1 to Class 12.

The main objective of the IMO is to promote excellence in the field of mathematics and to identify talent among students at an early age.

Key Highlights of IMO

IMO Exam Pattern

The IMO exam is conducted in two levels:

Level 1:

This level is open to all students from Class 1 to Class 12.

Note: For Class 1 and 2, the Achievers section includes questions of 2 marks each instead of 3.

Level 2:

Only the top 5% of students (class-wise and zone-wise) from Level 1 are eligible for Level 2. This level is applicable only for Class 3 to Class 12.

• The Level 2 exam is more analytical and advanced in terms of difficulty.
• It tests higher-order thinking skills.

IMO Syllabus

The IMO syllabus is based on the respective class curriculum as prescribed by CBSE, ICSE/ISC, and various state boards.
