If you ask an Arts student about GS Paper 3, they will say, “I can handle Economy, but Science & Tech scares me.” They start reading Class 6-10 General Science NCERTs, trying to memorize the “Speed of Light” or “Chemical Formulas.” Science and Technology for UPSC

Stop. You are preparing for 2026, not 1990. UPSC no longer asks “General Science” (Physics/Chemistry). They ask “Technology” (Application).

  • Old Pattern: “What is a Virus?”

  • New Pattern: “How does an mRNA Vaccine work?”

At Trademark IAS, we bridge the gap between “Arts” and “Science.” Here is the Science and Technology for UPSC strategy for the non-engineer.

1. The “4-Pillar” Syllabus Science and Technology for UPSC

Stop reading random science news. Focus only on these 4 High-Yield Pillars:

Pillar A: Biotechnology (The King)

  • Weightage: Highest. (Vaccines, GM Crops, DNA Technology).

  • Focus: CRISPR-Cas9, Stem Cells, Cloning, Diseases (Dengue, Malaria, COVID variants).

  • Source: Biology NCERT Class 12 (Last 4 Chapters) + Newspaper.

Pillar B: Space Technology (The Pride) Science and Technology for UPSC

  • Focus: ISRO Missions (Gaganyaan, Chandrayaan), Orbit Types (LEO, GEO), Launch Vehicles (PSLV vs GSLV).

  • Source: ISRO website FAQ section is gold.

Pillar C: IT & Communication (The Future) Science and Technology for UPSC

  • Focus: 5G/6G, Artificial Intelligence (AI), Blockchain, Cryptocurrency, Quantum Computing.

  • Tip: Know the difference (e.g., Difference between Augmented Reality and Virtual Reality).

Pillar D: Defense & Nanotech

  • Focus: Missiles (Ballistic vs Cruise), Submarines (Scorpene class), Nanomaterials.

2. Resources: Book vs. Current Affairs Science and Technology for UPSC

  • The “Book” Mistake: Books like Ravi P Agrahari are good, but Science evolves every day. A book printed in 2024 won’t have the 2025 AI updates.

  • The Winning Combo:

    • Base: Read NCERT Class 6-10 (Only if your basics are zero).

    • Core: “Science Reporter” Magazine (Selective reading) or a Coaching Monthly Magazine.

    • Sunday: Read the “Science & Tech” page of The Hindu.

3. How to Read Science News? Science and Technology for UPSC

Don’t read the technical jargon. Ask 3 questions:

  1. What is it? (Definition).

  2. How does it work? (Basic mechanism).

  3. Why is it useful? (Application for humanity).

    • Example: CRISPR.

    • What? Gene editing tool.

    • How? Acts like molecular scissors.

    • Use? Curing genetic diseases/Making pest-resistant crops.

4. Mains Strategy (GS Paper 3)

In Mains, Science is about “Indigenization”.

  • Question: “Discuss the achievements of Indians in Space Technology.”

  • Strategy: Don’t just list satellites. Discuss socio-economic impact (Tele-medicine, Disaster warning).

Conclusion

Science & Tech is the only subject where you can predict questions. If “Generative AI” is in the news, a question on AI is guaranteed. Don’t fear the subject; fear missing the newspaper.

Confused by “Biotech”? We have created a “Science Simplified” PDF module specifically for Arts students. It explains DNA, RNA, and AI in simple language.
