Students who fail to complete the registration within the stipulated timeline will be disqualified from INO 2026, irrespective of their NSE performance.
The Indian National Olympiad (INO) is the second and most critical stage in India’s Olympiad selection pathway, conducted in the following subjects:
INMO – Mathematics
