It’s designed for students who study Mathematics in school and follows the curriculum set by CBSE, ICSE, and State Boards. iOM provides a chance for students to measure their skills on an international scale.

Participating in iOM helps students build a strong foundation in Mathematics, aligning with what they’re learning in school. After the Olympiad, students receive a detailed report highlighting their strengths and areas for improvement, motivating them to excel academically. iOM doesn’t just stop at the school level. It recognises and rewards talented math students at both national and international levels.

- The
**International Olympiad of Mathematics (iOM)**level 1 is open to students from 1st to 12th grade. - In level 2, those who secured a spot among the top 1000 ranks in each class in level 1 can participate.
- For level 3, only the students holding the rank 1 position from class 6th to 12th in level 2 are eligible to take part in the exam.
