IOQM 2025 Question Paper with Answer Key

What is Mathematics Olympiads?

The International Mathematical Olympiad (IMO) is a mathematical olympiad for pre-university students, and is the oldest of the International Science Olympiads. It is “the most prestigious” mathematical competition in the world. The first IMO was held in Romania in 1959. It has since been held annually, except in 1980. More than 100 countries participate. Each country sends a team of up to six students, plus one team leader, one deputy leader, and observers.

Main Objective of IMO

Math Olympiad is a competitive exam that assesses students for their mathematical skills and abilities. The primary objective of this exam is to instill a competitive mindset in students. Unlike school exams, olympiad exams are intended to unveil the actual meaning of math learning.

Eligibility Criteria for IOQM 2024-25

Students born between August 1, 2006 and July 31, 2013, and studying in Class 8, 9, 10, 11 or 12, are eligible to write IOQM 2025. Please note that NO student born on or after August 1, 2013 will be allowed to write IOQM 2025.

The students must be eligible to hold Indian passport. Provisionally, students with OCI cards are eligible to write the IOQM 2025 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 (IMO), European Girls’ Mathematical Olympiad (EGMO), Asian Pacific Mathematics Olympiad (APMO). However, such students are provisionally eligible for selection at ALL prior stages, up to and including the International Mathematical Olympiad Training Camp (IMOTC) and the European Girls’ Mathematical Olympiad Training Camp (EGMOTC) provided they fulfil all other criteria. They are also provisionally eligible to write the selection tests at the IMOTC and EGMOTC. This policy is subject to revision without prior notice depending on any further orders issued by the courts, or by a competent Government authority.

The student must be residing and studying in India since 30 October 2023 or earlier
OR
must be studying in an Indian school system since 30 October 2023 or earlier.
If the student is residing abroad and is studying in an Indian school system then the student will have to come to India to write IOQM 2025 and the examinations of the subsequent stages (i.e Regional Mathematical Olympiad (RMO) 2025 and Indian National Mathematical Olympiad (INMO) 2026) in case s/he qualifies for these examinations. The student will be regarded as one who has enrolled from the Delhi-NCR and the same selection criteria for RMO 2025 and INMO 2026 will apply to him/her as for any student residing and studying in India who has enrolled from Delhi-NCR. The student will have to bear the expenses for the onward journey to India and the return journey from India.

The student must NOT have qualified (or scheduled to appear) class 12 board examination earlier than 30 October, 2025. Please note that forfeiture of class 12 board examination results in order to meet eligibility criteria of IOQM 2025 is NOT ALLOWED and any student adopting such a means will be DISQUALIFIED from the IOQM 2025.

The student must NOT have commenced (or planning to commence) studies in a university or equivalent institution by 1 June, 2026.

The INMO 2025 Awardees are eligible to write INMO 2026 directly WITHOUT qualifying through IOQM 2025 and RMO 2025 provided they fulfil the age criteria mentioned in point no.1, they haven’t commenced (or planning to commence by June 1, 2025) studies in a university or equivalent institution and they fulfil the eligibility criteria for IMO 2026 and EGMO 2027. Please note that the OCI students are not eligible to represent India in IMO 2026 and EGMO 2027.
● For the eligibility criteria for IMO 2026 please refer to https://imof.co/students-alumni/how-can-i-compete-at-an-imo/.
● Eligibility criteria for EGMO 2027:
A country’s contestants should normally be citizens or residents of that country, and should be selected through that country’s national Mathematical Olympiad or equivalent selection programme. Contestants must have been born less than twenty years before 1 April in the year of participation at the EGMO. Contestants must have been normally enrolled in full-time primary or secondary education on or after 1 December in the year prior to the EGMO, or, in the case of home-schooled students, must not have received a high-school diploma (or equivalent), and must be working toward such a credential on 1 December.

It will be the responsibility of the student to ensure that the above eligibility criteria are satisfied. In case it is found at any later stage of the programme that a student does not meet the eligibility criteria, he or she may be disqualified from the programme.

Qualification Criteria from IOQM to RMO

  1. A student has to score at least 10% of the total marks of the IOQM 2025 paper in order to be eligible to appear for RMO 2025 but this is NOT the sole qualifying criterion.
  2. Any student who has scored at least 10% of the total marks of the IOQM 2025 paper and enrolled for IOQM 2025 as a student of one of the classes 8,9,10,11 will be classified as a Category A student.
  3. Any student who has scored at least 10% of the total marks of the IOQM 2025 paper and enrolled for IOQM 2025 as a student of class 12 will be classified as a Category B student.
  4. The list of students who qualify for the RMO 2025 will be prepared according to the following rule:
    1. From each region (list of regions:  https://www.mtai.org.in/rmo-region-codes/)
      1. the top 200 students from Category A will qualify for RMO 2025 along with those tied in the 200th position;
      2. the top 40 students from Category B will qualify for RMO 2025 along with those tied in the 40th position;
      3. 5 additional girl students from Category A irrespective of the number of girl students qualifying in the top 200 students from Category A will qualify for RMO 2025 under Girls’ quota along with those girls tied in the 5th position.
    1. There is no separate Girls’ quota for Category B. A girl student of Category B can qualify for RMO 2025 from IOQM 2025 if and only if she is selected among the top 40 students in Category B as described in the previous section (point 4(a)ii. above).)
    1. any overseas student eligible to write IOQM 2025 will not be counted for generating cutoffs of the region from where s/he appears for IOQM 2025.
