What are the best resources for Science and Technology in UPSC?

Science and Technology is unique because it is heavily current affairs-driven, meaning no single textbook is sufficient. Your strategy must combine basic conceptual clarity with constant news tracking.

• For foundations, selectively read NCERTs (Class 6–10) and the Class 12 Biology NCERT (specifically chapters on Biotechnology).
• For a structured overview of the static syllabus, Ravi P. Agrahari’s Science and Technology is the most popular reference, covering Space, Nuclear Research, and Nano-tech.
  However, the most critical resources are dynamic.
• Vision IAS PT 365 is essential for consolidating yearly tech news, while the Sunday edition of The Hindu provides vital depth on research breakthroughs.
• Focus on understanding how technologies like Generative AI, CRISPR, and Quantum Computing work rather than just memorising facts. Supplement this by checking official ISRO and DRDO websites for mission updates.
