Introduction
Science and Technology is an important and increasingly relevant component of BPSC Mains General Studies, mainly appearing in GS Paper-II. Questions are generally application-based, focusing on how scientific and technological developments impact society, economy, governance, environment and national security.
In BPSC Mains, Science & Technology questions are asked from areas such as space technology, defence, health and biotechnology, environment, renewable energy, information technology, cyber security, disaster management and emerging technologies. The emphasis is not on technical details, but on practical use, benefits, challenges and policy relevance, especially for India and Bihar.
