INMO is an acronym for India National Mathematical Olympiad. INMO is second step of the ladder for International Mathematical Olympiad (IMO). INMO is organized by Homi Bhabha Centre for Science Education (HBCSE) on the behalf of National Board of Higher Mathematical (NBHM). INMO’s only aim is find mathematical talent in our country and build an elite team of Mathematicians for IMO. Students who qualify INMO examination are invited for International Mathematical Olympiad Training Centre (IMOTC). In this post we aim to provide you detailed information on INMO eligibility criteria, schedule, registration process, exam dates, selection procedure, result and previous year papers.

INMO 2018 Registration Process

  • There is no specific process for India National Mathematical Olympiad registration. The students willing to participate in INMO 2018 will have to first take and qualify Regional Mathematics Olympiad 2017 (RMO 2017) by finishing in Top 30 scorers in his/her region.
  • The RMO is organized is 25 regions all over the country by the three conducting authorities namely Central Board of Secondary Education (CBSE), Navodaya Vidyalaya Samiti (NVS) and Kendriya Vidyalaya Sangathana (KVS). You can find the registration process for RMO here.
  • INMO Syllabus

    The INMO 2018 Syllabus is pre-degree college mathematics. Following topics will be covered in the INMO question paper:

    • Arithmetic of Integers • Inequalities
    • Geometry • Elementary Combinatorics
    • Quadratic Equations & Expressions • Probability Theory
    • Trigonometry • Number Theory
    • Co-ordinate Geometry • Finite Series & Complex Numbers
    • System of Linear Equations • Elementary Graph Theory
    • Permutations & Combinations • Factorization of Polynomial

    The syllabus does not include calculus and statistics. The syllabus is of class XI and XII levels but are bundled with higher difficulty level and sophistication.

    India National Mathematical Olympiad 2018 examination will be a three hour written test. The INMO 2018will have only six problems. These six questions will be descriptive in nature.
