INMO 2026: Exam Date, Registration, Syllabus, Paper, Cutoff and Result

The Indian National Mathematical Olympiad (INMO) is the third stage of India’s Mathematical Olympiad programme. Students reach INMO after qualifying through RMO, and the best performers in INMO move to the International Mathematical Olympiad Training Camp (IMOTC). HBCSE states that INMO is held on the third Sunday of January and that the top INMO students are invited to IMOTC from April to May.

For the 2025–26 cycle, INMO 2026 was held on 18 January 2026. The official paper shows a 4.5-hour exam with a maximum of 102 marks, and the results have already been published by HBCSE. This makes INMO 2026 a completed official cycle, so students can now check the exam paper, result, cutoff, certificate details, and camp selection information from official sources.

INMO Registration

INMO does not have a broad open public registration like school olympiads. Students become eligible for INMO after qualifying through RMO, and then they must complete the official registration process within the announced window. For INMO 2026, HBCSE stated that registration was to begin on 6 January 2026 and the portal was to close at 17:30 on 13 January 2026. HBCSE also stated that students who did not register by the closing date would be disqualified from INMO 2026.

INMO Syllabus

HBCSE uses a broader Mathematical Olympiad syllabus framework for RMO and INMO. Students are expected to be familiar with NCERT Mathematics of Classes 8, 9, and 10, and HBCSE gives special importance to algebra, combinatorics, geometry, and number theory. HBCSE also clearly states that the difficulty level increases from RMO to INMO to IMO, so INMO preparation must go significantly beyond routine school mathematics.

Core INMO Syllabus Areas

Area	Important topics
Algebra	Inequalities, progressions, systems of equations, polynomials, binomial theorem, sequences, complex numbers, functional equations
Geometry	Triangles, quadrilaterals, circles, Euclidean geometry, trigonometric identities, polygons, coordinate geometry, conics, vectors
Combinatorics	Basic enumeration, pigeonhole principle, recursion, elementary graph theory
Number Theory	Divisibility and olympiad-style number theory topics

INMO Cutoff 2025

If you are searching for the INMO cutoff 2025, the official INMO 2025 Result page gives the category-wise cutoffs used for selection to IMOTC 2025. The cutoffs were:

Category	Class Group	Cutoff
Category A	Classes 8 to 11	31
Category AG	Girls’ quota, Classes 8 to 11	20
Category B	Class 12	34

These are official HBCSE cutoff marks for selection to IMOTC 2025, not for writing INMO itself.

INMO 2026 Result

The INMO 2026 results have been officially published. HBCSE’s result page lists the category-wise cutoffs for selection to IMOTC 2026 and identifies the successful candidates who qualified as INMO 2026 Awardees. The published cutoffs were:

Category	Class Group	Cutoff
A	Classes 8 to 11	37
AG	Girls’ quota, Classes 8 to 11	24
B	Class 12	47

The same official result page also states that the selected awardees were eligible to attend IMOTC 2026 at Chennai Mathematical Institute, Chennai, Tamil Nadu, from 6 May to 1 June 2026.

INMO Certificate

HBCSE states that all successful candidates listed in the official INMO 2026 results receive an INMO Awardee Certificate.
The same result page also notes that performance cards for all students who appeared in INMO 2026 were made available for download from 24 March 2026.
In addition, the 2025–26 Mathematical Olympiad brochure states that all students receive participation certificates, while awardees receive the relevant recognition and prizes.

INMO Certificate Details

Document	Status
INMO Awardee Certificate	Given to successful candidates
Performance Card	Available for all appearing students from 24 March 2026
Participation Certificate	Mentioned in the 2025–26 brochure for all students

INMO Camp

The major camp after INMO is IMOTC.
HBCSE states that the top students from INMO are invited to the International Mathematical Olympiad Training Camp, which is held from April to May.
For the 2025–26 cycle, the official INMO 2026 result page states that IMOTC 2026 was held at Chennai Mathematical Institute from 6 May to 1 June 2026.
HBCSE’s selection criteria document states that the top 60 students from the INMO 2026 merit list were selected for IMOTC 2026, with 48 from Category A, 12 from Category B, and 5 additional girls from Category A in the girls’ quota.

INMO Olympiad Pathway

The official mathematical olympiad progression is:

Stage	Exam / Process
Stage 1	IOQM
Stage 2	RMO
Stage 3	INMO
Stage 4	IMOTC
Final outcome	Selection of the Indian team for IMO

HBCSE states that around 65 students are invited to IMOTC, and six students are eventually selected to represent India at the IMO on the basis of tests held during camp.

How to Prepare for INMO

A strong INMO preparation plan should focus on:

advanced proof-writing
full-length written solutions
algebra, combinatorics, geometry, and number theory
Solving older Olympiad papers
reading standard olympiad books listed by HBCSE

Since HBCSE explicitly notes that the difficulty level rises from RMO to INMO to IMO, preparation for INMO should be deeper, slower, and more proof-oriented than RMO preparation.
