MATHEMATICS! For many students, this word means fear and confusion. But there are a few special ones that take it as an adventure. For them, it is a subject full of pattern puzzles and logic, waiting to be explored. If you belong to that group, the Regional Mathematical Olympiad is a perfect test for you. It is India’s most respected exam for students who enjoy exploring the logic behind numbers. It is the second stage of the national Olympiad program and opens the path to bigger contests like INMO and IMO. But before you decide to jump in and take the test, it is important to understand what this exam looks like. In this guide, you will find all the key details regarding the RMO 2025 Exam pattern, syllabus, marking rules, dates, and eligibility.

RMO 2025 Exam Pattern
The following table depicts the RMO 2025 exam pattern :
| Feature | Details |
| Duration | 3 hours for the entire paper |
| Number of Problems | 6 descriptive problems |
| Mode | Pen & paper (offline) exam |
| Language | English, Hindi and regional languages as per region |
| Format | Each problem expects a full solution, reasoning and explanation |
The RMO 2025 Exam pattern is such that it asks for full, detailed answers, and it doesn’t have short-answer questions or MCQs! Each question asks for a description and is mentally challenging!
Syllabus Overview
Now that we have a clear understanding of the RMO 2025 exam pattern, let us look at the RMO 2025 syllabus too. Here are the broad topic areas commonly covered in RMO 2025:
| Topic Area | Key Ideas to Study |
| Number Theory | Divisibility, modular arithmetic, Diophantine equations, integer properties |
| Algebra | Polynomials, inequalities, functional equations, sequences |
| Geometry | Euclidean geometry, circles & triangles, coordinate geometry, basic transformations |
| Combinatorics & Graph Theory | Counting methods, permutations and combinations, pigeonhole principle, simple graphs |
While your school syllabus provides the base, RMO requires stepping beyond it. You must connect ideas, apply them creatively, and write logical steps clearly.
RMO 2025 Exam Dates
Let us also have a look at the RMO exam dates for 2025:
| Event | Date (2025) |
| Registration & Admit Card | Will be announced by your regional RMO coordinator |
| RMO Exam Date | 16 November 2025 (all regions) |
| Time | 13:00 – 16:00 (1:00 pm – 4:00 pm) |
Tip: The exam is held regionally on one specific day, so make sure to check your school or centre notification beforehand and mark it in your calendar accordingly.
RMO 2025 Marking Scheme
| Aspect | What to Know |
| Marks per Question | Approximately 17 marks per problem |
| Total Marks | Around 102 marks for the full paper |
| Partial Credit | You earn marks for correct methods, even if the final answer is missing |
| Presentation Counts | Clear logic, defined steps, and neat writing help you score |
| Negative Marking | None stated — focus is on the correctness of work |
Because of this scheme, you should focus on writing correct logical steps, not rushing for answers. Even if you cannot fully solve a problem, a partial but correct method can earn you good marks.
Eligibility Criteria for RMO 2025
| Criterion | Details |
| Who can appear | Students who qualified in the IOQM of the respective year |
| Class-levels | Usually, classes 8 to 12 are eligible |
| Region | Each school corresponds to a regional centre; you appear in your region |
| Next Stage Selection | Top students from each region (e.g., ~30 from classes 8-11, ~6 from class 12) qualify for INMO |
This means you must first clear IOQM, and then you become eligible for RMO. Check your regional rules because some regions may vary slightly.
Difficulty Level of the RMO Exam
- The questions in RMO are much harder than typical school or board exams.
- Each problem expects a clear logical argument, not just plug-in answers.
- You will see ideas combined from multiple areas (for example: algebra + number theory).
- Time management is important because 6 problems in 3 hours means you must think rather than hurry.
- Success depends on building a deep understanding and regular practice, not last-minute reading.
Conclusion
We hope by now, you have a clear idea of how the RMO 2025 exam works! From the RMO 2025 Exam pattern, syllabus and marking scheme, we have provided all the necessary details.
