SOF Olympiad 2025-26: Overview of All Exam Levels
The SOF Olympiads 2025-26 are conducted across multiple levels to assess students’ knowledge, reasoning abilities, and subject proficiency. Each Olympiad follows a structured pattern designed to evaluate skills progressively. Most SOF exams, including NSO, IMO, IGKO, IEO, and ICSO, are conducted in a single level, where students from Classes 1 to 12 participate directly.
However, a few Olympiads like the International Mathematics Olympiad (IMO) and National Science Olympiad (NSO) may include a Level 2 exam, depending on student performance and eligibility.

Every level of the SOF Olympiad aims to encourage academic excellence and expose students to competitive exam patterns at an early age. The structured exam levels help break down the competition into manageable stages, allowing students to showcase their potential at national and international platforms.
