INMO 2023 Olympiad - Full Form, Exam Dates, Registration, Login

The INMO full form is the Indian National Mathematical Olympiad, the third stage of HBCSE IMO. Previously, the RMO exam's best-performers were qualified for the third stage, but due to the pandemic, PRMO and RMO were canceled, and the IOQM exam was held. On this page, students can find INMO 2023 dates, INMO login, registration details, etc.

What is INMO 2023?

In 1989, Indian National Mathematical Olympiad was conducted for the first time and had been conducted every year since then. Every year around 45 students are selected from the INMO exam for the International Mathematical Olympiad Training Camp (IMOTC). The time duration of the exam is four-hour and has six questions. The questions need to be solved on the answer sheet and submitted along with the rough sheets after exams. The difficulty level compared to RMO is more.

Students who clear the INMO (Indian National Mathematical Olympiad) receive certificate and invitation expenses for lodging-boarding in training camp at HBCSE Mumbai. Participants who qualify for NHBM will be eligible to participate in the IMO (International Mathematical Olympiad). The Ministry of HRD provides the fare for international tickets. For the global competition, a team of 6 selected students goes to the decided international venue.

Given below are the INMO 2023 key highlights.
