The Maths Olympiad Programme which leads to participation in the IMO- International Mathematical Olympiad,constitutes of the following stages:
Stage 1: Regional Mathematical Olympiad (RMO)
Regional Mathematical Olympiad is held in each region normally between September and the first Sunday of December each year. A regional coordinator makes sure that at least one centre is provided in every district of the region. RMO is a 3-hour written test which contains about 6 to 7 problems. All high-school students up to class XII are eligible to appear for RMO. To appear for RMO, interested students should get in touch with the RMO co-ordinator of their region well in advance, for enrolment and payment of a nominal fee.
Each regional coordinator has the freedom to prepare his/her own question paper or to obtain the question paper from NBHM. The regions which opt for the NBHM question paper hold this contest on the 1st Sunday of December. On Based on theirperformance in RMO, certain number of students from each region are selected to appear for the second stage. The regional coordinators charge nominal fees to meet the expenses for organizing the contests.
Stage 2: Indian National Mathematical Olympiad (INMO)
Indian National Mathematical Olympiad is held on the first Sunday of February every year at differentcentres in different regions. Just the students who are selected on the basis of RMO from various regions are eligible to appear for the INMO. It is a 4-hour written test. Its question paper is set centrally and the test is common throughout the country. Only the top 30-35 performers in INMO receive a merit certificate.
Stage 3: International Mathematical Olympiad Training Camp (IMOTC)
This is a training level for the INMO certificate awardees. They are invited for a month long training camp (for junior batch) conducted in May-June, each year. Also in addition, INMO awardees of the previous year who have satisfactorily completed the postal tuition throughout the year are again invited for a second round of training (called the senior batch).
Stage 4: International Mathematical Olympiad (IMO)
A leader and deputy leader are chosen by the NBHM from among mathematics teachers/researchers involved in the Mathematics Olympiad activity.So the team selected at the end of the camp, the leader and the deputy leader, represent India at the International Mathematical Olympiad that is normally held in July in a different member country of IMO each year. The IMO consists of two written tests held on two days with a gap of at least one day. Both the tests are of four-and-a-half-hours.
