SOF International Mathematics Olympiad (IMO)- All You Need to Know

IMO or the International Mathematics Olympiad is a mathematics-based competition conducted each year by the Science Olympiad Foundation (SOF). The Olympiad conducted for students of Class 1 to 12 aims to identify and support students who show a potential of becoming future scientists or technologists. IMO also helps students compete with other students from across the country or world. It helps them judge their mathematical skills. The results of the IMO give students an idea of their academic growth. A Student Performance Report (SPR) received after participating in the Olympiad provides a detailed analysis of the student’s performance.

SOF, the organiser of IMO, is an educational organisation involved in the academic development of students. The foundation organises a number of national and international Olympiads including National Cyber Olympiad (NCO), National Science Olympiad (NSO), International Mathematics Olympiad (IMO), International English Olympiad (IEO), International Company Secretaries Olympiad (ICSO) and International General Knowledge Olympiad (IGKO).

IMO – Result declaration

The Olympiad results are usually declared within 8 weeks of the examination. Students can collect their results from their respective schools as the SOF sends the results directly to the registered schools. Alternatively, students can also check their results on the official website of SOF. The exact dates for the IMO result declaration are subject to the discretion of SOF. However, results are usually announced tentatively by December – January for Level 1 and for Level 2 by March – April.

Students participating in the IMO are also given a Student Performance Report (SPR). It is a detailed report of students’ performance in the Olympiad. SPR proves beneficial for students and their parents as it provides an extensive performance analysis. An SPR can help students understand their strengths and weaknesses. There are six sections in the SPR:

Section A: Marks achieved by the student as well as the rank achieved at School/City/Zone/International level

Section B: Section wise performance score of the student

Section C: Answers provided by the student, performance comparison with other students and the correct answers to the questions asked in the Olympiad

Section D: Percentage score analysis of the student with a comparison with the Class, City, Zone and International level

Section E: Average marks analysis comparison for students at the School, City, Zone and International level

Section F: Student’s performance in the Olympiad exams in the last 8 years
