Indian National Mathematical Olympiad

The Indian National Mathematical Olympiad (INMO) is a highly selective high school mathematics competition held annually in India. Since its debut in 1989, it has served as the final round of the Indian Olympiad Qualifier in Mathematics. It is the third tier in the Indian team selection procedure for the International Mathematical Olympiad and is conducted by the Homi Bhabha Centre for Science Education (HBCSE) under the aegis of the National Board for Higher Mathematics (NBHM).

The Mathematical Olympiad Program (MOP) comprises a five-stage process overseen by the National Board for Higher Mathematics (NBHM). The initial stage, the Indian Olympiad Qualifier in Mathematics (IOQM), is organized by the Mathematics Teachers’ Association (India). Subsequent stages are conducted by the Homi Bhabha Centre for Science Education (HBCSE).

Eligibility and participant selection process
In order to be eligible to take the INMO, a participant must be either an Indian citizen or an Overseas Citizen of India. Only Indian citizens may join the Indian IMO team. In addition, all participants, regardless, must meet qualification indices determined by previous rounds of the IOQM.

All stages are divided into three categories:

Category A, catering to participants in Class VIII to XI. & Category AG, female supernumerary participants in Class VIII to XI.

Category B, tailored for Class XII participants.

Indian Olympiad Qualifier in Mathematics (IOQM)
It is a 30-question objective examination of 3 hours duration. It is usually held on the first Sunday of September. It is similar to the AIME conducted in the USA.

Structure & Pattern of the INMO
It is a 6-question subjective examination of 4.5 hours duration. It is usually held on the third Sunday of January. It is similar to the USAMO conducted in the USA.

Top performers who qualify the IOQM, need to undergo another round of further testing, RMO. It is a subjective examination of the same pattern as that of the INMO but of 3 hours duration. Finally, participants for the INMO are shortlisted. The INMO is conducted to select students for the IMOTC, which is further conducted to select the Indian team for the IMO. The topics asked are generally equivalent to those taught at high school level, except calculus. The difficulty of the problems tends to be generally higher than what is done in schools, with strong focus on application of concepts.

International Mathematical Olympiad Training Camp (IMOTC)
INMO qualifying students are invited to the four-week IMOTC which will be hosted by the CMI in 2024. For first-time participants, the camp runs from first week of May to the end of May, while previously participated candidates join about one week later. Four selection tests and two practice tests are conducted, and the top six students qualify to represent India at the IMO.

Pre-departure Training Camp (PDC)
The selected team of six students undergoes an additional two-week training and orientation session before departing for the IMO.

International Mathematical Olympiad (IMO)
The six-member team, accompanied by a leader, deputy leader, and observer, represents India at the IMO, held in July each year in a different member country. The Ministry of Human Resource Development (MHRD) finances international travel, while NBHM(DAE) covers other associated expenditures.

Post-IMOTC
Students who qualify the INMO and attend the IMOTC are eligible to appear directly in the INMO in the subsequent year.
