RMO Selection Criteria 2026 For Both Category A & B

RMO Selection Criteria 2026

Students selected through IOQM become eligible for the Regional Mathematical Olympiad (RMO) if they fulfil the applicable selection requirements. HBCSE has scheduled RMO 2026 for November 15, from 1 PM to 4 PM. To be eligible for RMO 2026, a student must score at least 10% of the total marks in the IOQM 2026 paper. However, this is only the minimum qualifying requirement and is not the only selection criteria for students.

Students who meet this minimum score are divided into two categories based on the class in which they were enrolled while appearing for IOQM 2026.

Category A Eligibility

Students who:

• Score at least 10% of the total marks in IOQM 2026, and
• Were enrolled in Class 8, 9, 10, or 11

are classified as Category A students.

Category B Eligibility

Students who:

• Score at least 10% of the total marks in IOQM 2026, and
• Were enrolled in Class 12

are classified as Category B students.

RMO qualification is decided regionally. Each region selects a number of students from Categories A and B depending on their IOQM performance.

• Category A, the top 200 students from each region are eligible for RMO 2026. Students who tie with the 200th-ranked student are also included on the qualification list.
• Category B, the top 40 students from each region are eligible. As with Category A, students tied for 40th place are also eligible.

Therefore, simply achieving 10% in IOQM does not guarantee immediate RMO qualification. Students should aim for a high ranking in their respective category and region.

Minimum Marks Required to Be Eligible for RMO 2026

Students must score at least 10% of the total marks to be considered for RMO selection. But this 10% criteria will not be the sole consideration for RMO 2026. The official IOQM-to-RMO selection criteria specify the following:

NOTE: There is no single uniform safe score for RMO 2026. A score that is sufficient in one region may be insufficient in another.

First, calculate your score using the official RMO answer key. Then compare it to the specific region and category. If your score is close to the estimate, continue to prepare and wait for the final selection list.

RMO 2026 Category A Selection Criteria

Students enrolled in Classes 8, 9, 10, and 11 of IOQM 2026 qualify as Category A if they satisfy the minimum mark requirement of 10%. For Category A, the top 200 students from each region are eligible for RMO 2026. Students who tie with the 200th-ranked student are also included on the qualification list. In addition, five girls from Category A are selected under the Girls’ quota, along with those tied at the fifth position.

RMO 2026 Category B Selection Criteria

RMO 2026 Category B is applicable to students enrolled in Class 12 for IOQM 2026 who fulfil the minimum mark requirement of 10%. The top 40 Category B students from each region, including those tied for 40th place, are eligible for RMO. Unlike Category A, Category B does not have a separate girls' quota.

What Happens If Students Are Tied at the Cutoff?

If students are tied at the last qualifying position, all tied students are qualified for RMO. Category A includes ties at the 200th position, while Category B includes ties at the 40th position.

RMO 2026 Selection Criteria: Key Points to Remember

Students preparing for RMO 2026 should keep these important points in mind:

1. A minimum score of 10% of the total IOQM 2026 marks is required for qualification.
2. Meeting the 10% requirement alone does not mean automatic RMO qualification.
3. Classes 8–11 are placed in Category A.
4. Class 12 students are placed in Category B.
5. Category A has 200 qualifiers from each region, plus eligible ties.
6. Category B has 40 qualifiers from each region, plus eligible ties.
7. Category A has an additional girls' quota of five students from each region, including ties.
8. Category B does not have a separate girls' quota.

Understanding the RMO selection criteria for 2026 can help students set realistic goals and prepare plans accordingly. The most important point is that the 10% score is a minimum qualifying threshold rather than a guaranteed selection mark. Final qualification depends on regional ranking, category, ties, and the applicable girls' quota.

Students aiming for RMO should therefore focus not only on crossing the 10% minimum IOQM score but also on achieving a strong rank within their respective category and region.

RMO Selection Criteria 2026: Conclusion

The RMO Selection Criteria 2026 is based on a combination of the minimum IOQM qualifying score, category, regional ranking and applicable quota rules. Students need to score at least 10% of the total IOQM 2026 marks to be considered for selection, but this minimum score does not guarantee RMO qualification. Category A includes students from Classes 8 to 11, while Class 12 students are considered under Category B.

For each region, the top 200 eligible Category A students and top 40 eligible Category B students qualify, with students tied at the respective cutoff positions also included. Category A also has an additional girls’ quota, while Category B has no separate girls’ quota. Students should therefore focus on achieving a strong IOQM score and rank within their respective category and region for RMO 2026 selection.
