Preparing for the 71st BPSC Mains 2025-26? The Science & Technology section (Section III of GS Paper 2) is crucial, typically carrying 40-80 marks. Questions emphasize the role and impact of S&T in India’s development, emerging technologies (e.g., nano, nuclear, space, IT), environmental applications, energy solutions, and Bihar-specific linkages (e.g., disaster management, industrial growth).
This year-wise compilation covers all Science & Technology-related questions from GS Paper 2 for the 63rd to 70th BPSC Mains (2017–2024). Marks are usually 38 for long answers (analytical) and 20 for short notes. Focus on current developments (ISRO missions, nuclear policy, nanotechnology applications) and positive/negative impacts for strong answers.
Key Trends for 71st BPSC
- Recurring Themes: Nuclear energy (pros/cons), space technology, emerging tech (nano, IT), energy crisis solutions, environment & pollution via tech, S&T for development (social, industrial, sustainable).
