INMO Exam 2025: Complete Student Guide

Students are eligible for INMO 2025 if they:

• Qualify the IOQM (Indian Olympiad Qualifier in Mathematics).
• Are in classes 8–12 as per the latest HBCSE guidelines.
• Belong to the top 28 from each region (classes 8–11), top 6 from class 12, or top 5 girls per region from classes 8–11 (girl quota).
• Fit within overseas quotas for CBSE/ICSE/KV students abroad (max. 5 each category).
• Are previous year INMO awardees (direct entry for current year).

There is no direct open registration; eligibility is via IOQM merit only.

The INMO 2025 exam is tentatively scheduled for February 2025. The official date will be announced by HBCSE on their website closer to the time. Eligible students should check for updates regularly.

Qualifying for the INMO is highly competitive and requires advanced problem-solving skills. Key points include:

• Only top students from IOQM can attempt INMO.
• The exam presents six complex, proof-based questions.
• Deep conceptual understanding of algebra, geometry, number theory, and combinatorics is mandatory.
• Self-prep using previous year papers and intensive practice is needed for success.

Yes, qualifying or ranking in the INMO or Math Olympiad is highly regarded by colleges in India and internationally.

• INMO performance demonstrates strong problem-solving, logical reasoning, and dedication.
• It enhances academic profiles for admissions, scholarships, and STEM opportunities.
• Leads to participation in camps like IMOTC and potential selection for the IMO team.

The INMO syllabus for 2025 covers advanced mathematics topics relevant for classes 8–12:

• Algebra: Polynomials, inequalities, factorisation, functional equations
• Geometry: Euclidean geometry, circles, triangles, transformations
• Number Theory: Divisibility, modular arithmetic, primes, Diophantine equations
• Combinatorics: Counting, permutations, pigeonhole principle, graph theory basics

Calculus and statistics are generally not included.

You can access INMO previous year question papers and solutions for free from official sources and educational websites:

• Vedantu’s INMO resources section provides downloadable PDFs and solutions.
• The HBCSE Olympiad official site hosts a repository of past papers.
• Practicing these papers is crucial for self-assessment and exam readiness.

Qualifying the INMO offers significant academic and career advantages:

• Invitations to the prestigious IMOTC (International Mathematical Olympiad Training Camp).
• Eligibility to represent India at the International Mathematical Olympiad (IMO).
• Certificates, merit scholarships, and national recognition.
• Boosts college applications and enhances STEM career prospects.

Coaching for INMO is not compulsory, but it can provide structured guidance, practice, and expert feedback:

• Many top performers benefit from online INMO coaching and mock tests.
• Self-study with quality reference books and solving PYQs is also effective.
• Joining study groups and Olympiad forums can accelerate learning.

In the event of an INMO tie, the process is as follows:

• PRMO/IOQM scores are considered first for breaking ties.
• If there's still a tie, all names are submitted to HBCSE for committee review and final selection, as per official policy.

The INMO exam is a written, subjective test focused on mathematical proofs:

• 6 questions, each demanding a descriptive and logical explanation.
• 4-hour duration (typically 12:00 pm to 4:00 pm).
• No calculators allowed; only geometry tools are permitted.
• Conducted offline, available in English and Hindi.
• Partial credit awarded for correct reasoning, no negative marking.

Yes, special quotas in INMO allow:

• Top 5 girl students per region (from classes 8–11) to qualify even if not in the standard cutoff.
• CBSE, ICSE, and KV students abroad can qualify through specific overseas quotas (up to 5 in each category), as per HBCSE rules.
