The INMO is conducted by the HBCSE every year for students of classes 8 to 12 in India. The INMO exam is a key to the selection of IMO (International Mathematical Olympiad). It tests evolved problem-solving, logic, and proof-based reasoning. INMO qualifiers are invited for training camps to construct India’s IMO team. The INMO exam serves as the third stage for the top students who carried the Regional Mathematical Olympiad.
