Hello,

For the 2025-26 period, the Science Olympiad Foundation's IMO level 1 exams are on November 12, November 28, and December 12, 2025, with schools choosing one date, typically for 1 hour in the morning, while the actual International Mathematical Olympiad (IMO) is a separate, later event, but for school levels these dates are key.

I hope it will clear your query!!

The SOF IMO (International Mathematics Olympiad) Level 1 exam duration for the 2025-2026 session is exactly 1 hour (60 minutes).

The exam is conducted on multiple dates (Set A, B, and C) across November and December. The final date for Level 1, Set C, is December 12, 2025.

The test is an objective-type (MCQ) examination. For students in Classes 5 to 12, the paper contains 50 questions in total, covering Logical Reasoning, Mathematical Reasoning, Everyday Mathematics, and the Achievers Section.
