Science & Technology — UPSC DPP

🎯 Practice Science & Tech Questions Now →

The Science & Technology section spans space research, defence technology, biotechnology, and IT — tested in Prelims (GS Paper 1) and Mains (GS Paper 3). It's one of the fastest-moving parts of the syllabus, since ISRO missions, defence deals, and tech policy updates happen throughout the year.

Our Science & Technology DPP sheets combine static concepts (how satellites work, what biotechnology techniques involve) with current developments (recent ISRO launches, new defence systems, emerging tech policy) — so your prep stays current without extra effort on your part.

What's covered

• Space technology — ISRO missions, satellite systems, space policy
• Defence — indigenous defence systems, missile technology, strategic partnerships
• Biotechnology — genetic engineering, healthcare applications, agricultural biotech
• IT and emerging tech — AI policy, cybersecurity, digital infrastructure

What's inside each DPP sheet

• Chapter-wise MCQ questions (Prelims pattern)
• Answer key with simplified technical explanations
• Mains-style subjective questions (GS Paper 3)
• Model answers connecting technology to policy and applications

Frequently asked questions

Do I need a science background for this section?
No — explanations are written for non-specialists, focusing on what UPSC actually tests rather than technical depth.

How current are the questions?
Sheets are updated to include recent ISRO missions, defence developments, and technology policy news as they become exam-relevant.

Does this overlap with Current Affairs sheets?
There's some overlap by design — major Science & Tech news is covered here in depth, while our Current Affairs sheets give broader daily coverage across all subjects.
