INMO Eligibility Criteria

To appear for the INMO exam, students must meet the following eligibility criteria:

• Qualification through RMO: Students must qualify through the Regional Mathematical Olympiad (RMO), which is the first stage of the Olympiad process.
• Age Criteria: Students studying in Class 8 to Class 12 can appear for the INMO. However, there is no strict age limit, provided they are enrolled in a recognized school in India.
• Indian Citizenship: The exam is open only to Indian nationals or students enrolled in Indian schools.
• Exceptional Cases: In rare instances, students who perform exceptionally well in the PRMO (Pre-Regional Mathematical Olympiad) may be directly invited to take the INMO.

INMO Exam Pattern

The INMO exam consists of a rigorous assessment of a student’s mathematical abilities. The exam pattern is designed to test both problem-solving skills and conceptual understanding. Here's a detailed overview of the INMO exam pattern:

The questions are subjective and require detailed solutions. Unlike other competitive exams, the INMO does not follow a multiple-choice question (MCQ) format, making it imperative for students to present clear and logical answers.

INMO Exam 2026 Syllabus

While there is no fixed syllabus for the INMO 2026 exam, the questions are generally based on higher secondary level mathematics. The problems are often more advanced and demand a deep understanding of mathematical concepts. Below is a breakdown of the important topics covered for INMO Exam Syllabus are as follows:

Algebra

• Polynomials and Equations
• Sequences and Series
• Complex Numbers
• Inequalities

Geometry

• Euclidean Geometry
• Circle Theorems
• Coordinate Geometry
• Trigonometry

Number Theory

• Divisibility and Primes
• Congruences and Modular Arithmetic
• Diophantine Equations
• Fermat’s Theorem

Combinatorics

• Permutations and Combinations
• Pigeonhole Principle
• Graph Theory
• Probability Theory

Each of these topics requires extensive practice, and students are encouraged to study from various resources like textbooks, Olympiad handbooks, and problem sets from past exams.

How to Prepare for INMO 2026 Exam?

Preparation for INMO requires a blend of conceptual clarity, problem-solving skills, and the ability to think critically. Practicing INMO previous year questions with detailed answers plays a key role in understanding the exam pattern and improving accuracy. Here are some effective preparation tips to help you succeed:

• Study the Basics: Ensure that your foundation in topics like algebra, geometry, and number theory is strong. You cannot solve complex problems without a clear understanding of basic concepts.
• Solve Previous Year Papers: Practice solving INMO question papers from previous years. This will give you an idea of the difficulty level and the types of problems that appear in the exam.
• Focus on Problem Solving: INMO problems often require creative and innovative solutions. Regularly engage in problem-solving exercises and competitions to sharpen your skills.
• Join Coaching or Study Groups: Many students benefit from joining Olympiad training programs or study groups where they can collaborate with peers and learn from experienced mentors.
• Time Management: Since the exam requires detailed written solutions, time management is crucial. Practice solving problems under timed conditions to improve your speed and accuracy.
• Attend Training Camps: After qualifying for INMO, students have the opportunity to attend training camps where they receive guidance from experts. These camps provide additional resources and support to help students excel in the international rounds.

Benefits of Qualifying INMO Exam

Qualifying for the INMO exam opens up numerous opportunities for students. Here’s what successful candidates can expect:

• National Training Camps: Students who qualify for INMO are invited to attend a month-long training camp organized by HBCSE. These camps are designed to prepare students for the International Mathematical Olympiad.
• Scholarship Opportunities: Qualifying INMO students often receive scholarships and financial support from various institutions to pursue higher education in mathematics and related fields.
• National Recognition: INMO qualifiers receive certificates of merit, which are valuable additions to their academic profile. Many top universities in India and abroad recognize these achievements during the admission process.
• International Participation: After the national training camp, the best performers are selected to represent India at the International Mathematical Olympiad (IMO), one of the most prestigious global mathematics competitions.

INMO 2026 Selection Process

The results for INMO 2026 are expected to be declared between February & March. Once the results are announced, the selected candidates will be invited to participate in the next stage, which includes national training camps and further rounds leading to international participation.

How to Apply for INMO 2026?

The application process for the INMO exam is a bit different than conventional exams. Here’s how you can apply:

• Qualify RMO: Students must first qualify in the Regional Mathematical Olympiad (RMO) to be eligible for the INMO. The RMO is conducted across different regions in India.
• Registration: Once a student qualifies for RMO, they will automatically be registered for the INMO exam by their respective Regional Coordinators.
• Exam Fee: There is no separate fee for the INMO exam, as it is a part of the Indian Mathematics Olympiad program managed by HBCSE.
