The SOF NSO (National Science Olympiad) Class 9 Answer Key for the 2025-2026 Level 1 exam is expected to be released by the Science Olympiad Foundation (SOF) during December 2025.

The NSO exam is conducted in three sets (Set A, Set B, and Set C), and the answer keys are released separately for each set. Since the final NSO exam date (Set C) was held today, December 11, 2025, the official answer keys for all sets (A, B, and C) will be made available shortly this month on the official website, and the links will be updated on the provided page.

While the actual NSO question paper for the 2025 Level 1 exam has been administered (Sets A and B in November, Set C today, December 11, 2025), this sample paper is crucial because it:

1. Mirrors the Exam Pattern: It exactly reflects the structure of the Olympiad: 50 questions across Logical Reasoning, Science, and the Achievers Section, carrying a total of 60 marks.

2. Includes Key Topics: It covers the most important concepts from the Class 9 Science syllabus (Physics, Chemistry, and Biology), ensuring focused revision for the Level 2 exam (scheduled for February 2026).
