Some students fear math and try to get rid of it all the time. On the other hand, there are some who enjoy it, love it, and look at it as a challenge worth taking. <\/span>This third stage of India\u2019s Mathematical Olympiad demands clarity and right preparation. But the first step in your preparation definitely has to be knowing the syllabus details. Let us help you with that!<\/span><\/p>\n

INMO Exam: An Overview<\/span><\/h2>\n

The INMO exam<\/span><\/a> is conducted by the Homi Bhabha Centre for Science Education (HBCSE) under the National Board for Higher Mathematics. Only students who qualify for the Regional Mathematical Olympiad (RMO) are eligible.<\/span><\/p>\n

Students selected through INMO move forward to the International Mathematical Olympiad Training Camp (IMOTC). From there, the best performers represent India at the International Mathematical Olympiad (IMO).<\/span><\/p>\n

Here is a quick snapshot of the INMO 2026 exam. This table gives you all the key details in one place.<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n
