INMO 2026 Exam Date Reference

The official stages page gives the general timing pattern, while the official paper gives the exact 2026 date.

INMO Registration 2026

INMO does not follow a broad open registration model like school olympiads. Students become eligible after qualifying through RMO, and then they must register within the official window announced for that cycle. 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 warned that students who did not register by the closing date would be disqualified from INMO 2026.

INMO 2026 Paper Details

The official INMO 2026 paper confirms that the exam was a 4.5-hour subjective paper with a maximum of 102 marks. The instructions also state that all questions carry equal marks and that no marks are awarded for providing an answer without justification, which clearly shows that INMO is a proof-based written olympiad exam.

Who Appears for INMO?

Students do not apply directly to INMO through a general public route. They first qualify through RMO, and then eligible students register for INMO in the official window. HBCSE’s RMO 2025 results page states that students whose roll numbers appeared in the qualified region-wise lists were eligible to appear for INMO 2026 on 18 January 2026.
