INMO Eligibility Criteria 2025

As the RMO Examination has been successfully held, and now students are anxious to know about the next stage for IMO, i.e. the Indian National Mathematical Olympiad (INMO). The INMO exam attracts thousands of students from all over the country, but only 30 candidates are selected.
The goal of the Indian National Mathematical Olympiad is to bring secondary and higher secondary students together in a common competitive arena to showcase their passion and proficiency in Mathematics.
To participate in INMO, students must meet several eligibility criteria. In our article, we have shared with you the breakdown of the INMO Eligibility Criteria 2025.

When there is a tie between the scores of two candidates, The Pre-Regional math Olympiad (Pre RMO) score will be considered as the tiebreaker. In a case where even the Pre RMO score fails to break the score, the final list submitted to the HBCSE will consider all the candidates.

Olympiad

INMO Educational Qualification

The INMO educational qualification criteria ensure that students who are taking part in the examination are in the right academic phase for the competition:
  • Students should be enrolled for Class 9 to Class 12 during the academic year of the Olympiad. This educational criterion ensures that the competition is specifically designed for students who are currently enrolled in the pertinent mathematical coursework.
  • Students who are not in Class 9 or who have already completed Class 12 are not eligible. This restriction helps maintain the INMO Examination's focus on current high school students.

INMO Age Limit

The prescribed age limit for the INMO Examination as per the official notification has been discussed below-
  • Students must be born on or after 1st July 2004 - This INMO Age Limit ensures that the competition remains relevant for current high school students.
  • Students must not have completed Class 12 or an equivalent examination before the year of the Olympiad

INMO Geographical Criteria 

All students from every state and Union Territory of India are welcome to take part. This inclusivity ensures that students from diverse geographical locations have the opportunity to compete. There are no restrictions based on the student’s place of residence or educational institution. This criterion enhances equal opportunities for all students, irrespective of their location or school affiliation.

Participated in Previous Olympiad

Students who have taken part in the International Mathematical Olympiad (IMO) or have been chosen for the IMO Team previously are ineligible for INMO. This rule ensures that INMO functions as a platform for emerging talent, preventing former participants from re-entering the competition. Students who have successfully qualified for the Indian National Science Olympiad (INSO) may participate in the Indian National Mathematical Olympiad (INMO) as long as they fulfill all other requirements. This provides an opportunity for gifted students from various science Olympiads to take part in INMO.
