INMO Exam Answer Key 2026
The Indian National Mathematical Olympiad (INMO) is one of the most prestigious mathematics examinations in India. It is organised by the Homi Bhabha Centre for Science Education (HBCSE) under the Tata Institute of Fundamental Research. INMO is the third stage of the Mathematical Olympiad Programme and is part of the selection path leading to the International Mathematical Olympiad (IMO).
To reach INMO, students first clear the IOQM (Indian Olympiad Qualifier in Mathematics) and then the Regional Mathematical Olympiad (RMO). INMO tests deep mathematical thinking, logical skills, and problem solving over extended written answers. After the exam, students and teachers wait for the answer key to check solutions and estimate scores.
