A major national Olympiad programme in basic sciences and mathematics that connects to the international Olympiads is in operation in India. The Homi Bhabha Centre for Science Education is the nodal centre of the country for this programme. The programme aims at promoting excellence in science and mathematics among preuniversity students.
Among the sciences, the Olympiad programme in Astronomy (junior and senior level), Biology, Chemistry, Junior Science and Physics is a five stage process for each subject separately.
The mathematical olympiad programe is a five stage process conducted under the aegis of National Board for Higher Mathematics (NBHM). The first stage PRMO is conducted by the Mathematics Teachers’ Association (India). All the remaining stages are organized by Homi Bhabha Centre for Science Education (HBCSE).
Science Olympiad
* The national Olympiad programme of 202021 in Science subjects (Astronomy, Biology, Chemistry, Junior Science, and Physics) has been affected by the ongoing COVID19 pandemic. The information on this page relates to the usual procedure of the Science Olympiads, and may not hold for the programme in 202021 due to the special circumstances prevailing in the country. Please check here for procedures to be adopted for the 202021 cycle.
Stages of Science Olympiad
The National Science Olympiad starts with an examination held at nearly 1400 schools across the country and culminates with the international Olympiads at different corners of the world. The national level examinations are designed to assess conceptual understanding, logical reasoning, laboratory skills, and above all, the ability to apply problemsolving skills to novel situations, both theoretical and experimental. Training is included from the third stage of the programme and the first two stages do not necessarily require any specialised coaching outside the regular school system.
Stage 1:
The first stage examination, the National Standard Examination (NSE) is the organisational responsibility of the Indian Association of Physics Teachers (IAPT). The academic responsibility for Chemistry and Biology rests with the Association of Chemistry Teachers (ACT) and the Association of Teachers in Biological Sciences (ATBS) respectively, while Physics, Astronomy and Junior Science are handled by IAPT itself. The NSEs are tests with objective type questions and are offered in English and Hindi, with additional languages also available in Physics. The syllabus is broadly equivalent to up to Class XII (for Astronomy, Biology, Chemistry and Physics) and Class X (for Junior Science) of the Central Board of Secondary Education (CBSE). However, the questions in all levels of Olympiads (including NSEs) may be expected to be of a higher difficulty level than the board examinations. These examinations are held close to the end of November every year at nearly 1400 centres across the nation. Students can register for this preliminary stage at their own schools. The registration fee is Rs 100, which is the only fee that the student has to pay in the entire process up to the International Olympiads.
Stage 2:
The bestperforming students from the NSEs (approximately 300 in each subject) qualify for the second stage — the Indian National Olympiads (INOs). The responsibility of the programme from this stage onwards lies with HBCSE. The INOs are held in late January at around 18 centres across the country. The syllabus is the same as that of the NSEs. The tests consist of objective as well as long questions.
Stage 3:
The top students from the INOs (approximately 35 in each subject) are invited for the third stage, the OrientationcumSelection Camps (OCSCs) held at HBCSE from April to June. At these camps, orientation is provided to students for the Olympiad level of theoretical, experimental and observational (for astronomy) tasks. Emphasis is laid on developing conceptual foundations and problemsolving skills. Students are exposed to innovative experiments with a focus on conceptual and procedural understanding in experimental science. In astronomy, students are trained in basic notions in astrophysics, astronomical data analysis and night sky observations. Several theoretical and experimental/observational tests are held during the camp. On the basis of performance in these tests, few students (numbers specified below) are selected to represent India at the international Olympiads.
Stage 4:
The selected Indian teams undergo a rigorous training programme at HBCSE in theory and experiment and in case of astronomy, observational astronomy prior to their departure for the international Olympiads. Special laboratories have been developed in HBCSE for this purpose. Resource persons from different institutions across the country are invited to the training camps.
Stage 5:
The Olympiad programme culminates with the participation of the Indian students (46 in each subject) in the International Olympiads. The students are accompanied by 24 teachers or mentors. Almost every Indian student who has participated in the Science and Astronomy Olympiads has returned with a medal.

The PRMO question paper will be in English and Hindi.
Stage 2:
The second stage examination, the Regional Mathematical Olympiad (RMO) is a threehour examination with six problems. The RMOs are offered in English, Hindi and other regional languages as deemed appropriate by the respective Regional Coordinators. The problems under each topic involve a high level of difficulty and sophistication.
Stage 3:
The bestperforming students from the RMO (approximately 900) qualify for the third stage – the Indian National Mathematical Olympiad (INMO). The INMO is held on the third Sunday of January at 28 centres across the country.
Stage 4:
The top students from the INMO (approximately 35) are invited for the fourth stage, the International Mathematical Olympiad Training Camp (IMOTC) held at HBCSE from April to May. At this camp, orientation is provided to students for the International Mathematical Olympiad (IMO). Emphasis is laid on developing conceptual foundations and problemsolving skills. Several selection tests are held during this camp. On the basis of performance in these tests, six students are selected to represent India at the IMO. Resource persons from different institutions across the country are invited to the training camps.
Stage 5:
The selected team undergoes a rigorous training programme for about 810 days at HBCSE prior to its departure for the IMO.
Stage 6:
The Olympiad programme culminates with the participation of the students in the IMO. The students are accompanied by 4 teachers or mentors.
Eligibility of Mathematical Olympiad
Candidates born on or after August 1, 2000 and studying in Class 8, 9, 10, 11 or 12 are eligible to write PRMO 2019. Further, the candidates must be Indian citizens. Provisionally, students with OCI cards are eligible to write the PRMO, subject to conditions as explained below:
As per the orders of the Madras High Court, students with OCI status will not be eligible for selection to the Indian team in the International Mathematical Olympiad. However, such students are provisionally eligible for selection at ALL prior stages, up to and including the IMOTC provided they fulfill all other criteria. This policy is subject to revision without prior notice depending on any further orders issued by the courts, or by a competent Government authority.
It is each student’s responsibility to determine if she/he satisfies the eligibility norms for each stage of the Mathematical Olympiads. If, at any stage, it is found that the student does not meet the eligibility norms, she/he may face immediate disqualification from the programme.
Syllabus for Mthematical Olympiad
The syllabus for Mathematical Olympiad (regional, national and international) is predegree college mathematics. The areas covered are arithmetic of integers, geometry, quadratic equations and expressions, trigonometry, coordinate geometry, the system of linear equations, permutations and combination, factorization of polynomial, inequalities, elementary combinatorics, probability theory and number theory, finite series, and complex numbers, and elementary graph theory. The syllabus does not include calculus and statistics. The major areas from which problems are given are algebra, combinatorics, geometry, and number theory. The syllabus is in a sense spread over Class XI to Class XII levels, but the problems under each topic involve a high level of difficulty and sophistication. The difficulty level increases from RMO to INMO to IMO.
