GS 3 Syllabus Weightage: What Previous Year Questions Show
Questions by Subject, 2013 to 2026
All 285 questions of the 14 GS Paper 3 papers from 2013 to 2026 are sorted here by subject, one subject per question. Every subject has appeared in every paper. The table gives each subject's total and how its yearly average moved between the first four papers (2013 to 2016) and the last four (2023 to 2026).
| Subject | Questions (share) | A year, then to now |
|---|---|---|
| Economy (6 of 20 topics) | 73 (26%) | 7.25 to 4.00 |
| Internal security (5 of 20 topics) | 57 (20%) | 4.50 to 3.75 |
| Agriculture and food (4 of 20 topics) | 54 (19%) | 3.50 to 3.75 |
| Science and technology (3 of 20 topics) | 48 (17%) | 3.25 to 4.00 |
| Environment (1 of 20 topics) | 33 (12%) | 1.50 to 3.00 |
| Disaster management (1 of 20 topics) | 20 (7%) | 1.25 to 1.50 |
The Economy's Share Has Nearly Halved Since 2013
The Indian economy is still the largest subject over the whole period, with 73 questions. But it has shrunk, from 7.25 questions a year in 2013 to 2016 to 4.00 in the last four papers, which asked exactly four each. Its six topics are unchanged, so the reading load has stayed the same while the return on it has fallen.
Four Subjects Now Share GS Paper 3 Almost Equally
As the economy fell, other subjects rose. In the last four papers the economy, science and technology, internal security and agriculture each averaged between 3.75 and 4.00 questions a year. The gap between the largest and smallest subject fell from 6.00 questions a year to 2.50.
A paper with four equal subjects rewards breadth. There is no longer one dominant subject to concentrate on, and skipping any of the four costs about four questions, a fifth of the paper.
Environment: One Syllabus Topic, Over a Tenth of the Paper
The environment topic is one of twenty, yet it has produced 33 questions, 11.6 per cent of the paper, and has doubled from 1.50 a year to 3.00. Disaster management, also a single topic, has asked one or two questions in every paper without exception.
GS Paper 3 Syllabus Subject by Subject
Indian Economy: Growth, Budgeting, Liberalisation and Infrastructure
The economy's six topics cover planning and the mobilisation of resources, growth, development and employment; inclusive growth; government budgeting; the effects of liberalisation and industrial policy; infrastructure (energy, ports, roads, airports, railways); and investment models. Recent questions are specific. They name a scheme, an index or an instrument and ask how it works and what it achieves.
In 2026 the paper asked about the Digital Rupee and India's energy security; in 2025 it asked about the Fiscal Health Index and the Production Linked Incentive scheme, each time about how the instrument works.
Build the base from NCERT economics and the Economic Survey, and then read current policy for the schemes and indices that questions now name. The economy topics also meet GS Paper 2 wherever a question turns to how the Union and the states share money.
Agriculture and Food: Crops, Subsidies, Food Processing and Land Reforms
Agriculture's four topics are cropping patterns, irrigation, storage, transport and marketing of produce; farm subsidies, minimum support prices, the public distribution system, buffer stocks and food security, technology missions and animal rearing; food processing and its supply chains; and land reforms. The subject is steady, with exactly four questions in eleven of the fourteen papers.
In 2026 the paper asked about the inefficiency of agricultural marketing, with the part e-commerce can play, and about the subsidies and support given to farming; in 2025 it asked about supply chain management of farm commodities and the scope of food processing.
Food processing and supply chain management are easy to leave out, yet both appeared in 2025. The World Trade Organization angle on subsidies, asked in 2026, links this subject to international agreements.
Science and Technology: Applications, Indigenisation and New Fields
The three science topics ask for developments and their applications in everyday life; achievements of Indians and the indigenisation of technology; and awareness in IT, space, computers, robotics, nanotechnology, biotechnology and intellectual property rights. The subject has risen from 3.25 questions a year to 4.00.
In 2026 the paper asked how fast breeder and thermal nuclear reactors work and what agentic artificial intelligence means for India; in 2025 it asked about India's fusion energy programme and semiconductor manufacturing.
Questions ask what a technology is, how it works and what it means for India, often in one question. A catalogue of the year's launches is not enough; each item needs the mechanism and the application.
Environment and Disaster Management: Two One-Line Topics
The environment topic reads "Conservation, environmental pollution and degradation, environmental impact assessment". Recent papers have ranged across climate commitments, biodiversity frameworks, groundwater and waste. Disaster management is five words, disaster and disaster management, and its questions fall into two halves, one on the institutions that manage disasters and one on the hazards themselves.
Environment questions in 2026 covered the Kunming-Montreal global biodiversity framework and solid waste management; in 2025 they covered depleting groundwater and India's climate commitments under the Paris Agreement.
Disaster management questions in 2026 weighed rapid infrastructure building against disaster-risk reduction in ecologically sensitive areas, with the part communities play; in 2025 the paper asked about the causes of seawater intrusion into coastal aquifers.
Prepare both halves of disaster management: The national framework and its authorities, and what specific hazards do and what reduces their damage. Environment questions reward India-specific examples of both success and failure.
Internal Security: Extremism, Cyber Security, Borders and Security Forces
The five security topics cover the link between development and extremism; external state and non-state actors; communication networks, media, social networking, cyber security and money laundering; border areas and the link between organised crime and terrorism; and the security forces and agencies with their mandates. The subject has held close to four questions a year.
In 2026 the paper asked about fake news and disinformation, and about counterfeit currency and money laundering as sources of terror funding; in 2025 it asked about Left Wing Extremism and maritime security.
Region-specific questions recur, and Jammu and Kashmir, Ladakh and the North-East all appeared in the last two papers. The topic on forces and agencies rewards precise knowledge of which force does what. For the sea, see the guide to maritime security and piracy, which covers the 2025 question on maritime and coastal security.
How GS 3 Questions Are Framed
Directive Words and What Each Word Limit Allows
Discuss is the commonest instruction, in 91 of the 285 questions, followed by explain (40), examine (21) and suggest (18). Suggest is the mark of this paper. It appears 18 times here against 13 in GS Paper 2 and 2 in GS Paper 1, and it asks for a remedy, not just a diagnosis.
| Directive | Questions containing it |
|---|---|
| Discuss | 91 |
| Explain | 40 |
| Examine | 21 |
| Suggest | 18 |
| Critically | 15 |
| Comment | 10 |
| Elaborate | 9 |
| Analyse | 8 |
- 150 words (10 marks): An opening line, three developed points and a close. An economy or security question usually wants a mechanism, a consequence and a measure.
- 250 words (15 marks): Room to explain the mechanism rather than assert it, and to add a way forward.
- Many questions have two parts: Explain what something is, then discuss its effects or suggest measures. Answer both parts, in order.

How to Prepare for GS Paper 3
Preparing the Six Subjects in Proportion
The question papers point to a clear plan. Treat GS 3 as a paper of four equal subjects with two smaller ones, not as an economy paper.
- Give four subjects equal time: The economy, agriculture, science and technology, and internal security each return about four questions a paper.
- Give environment more than its one line: It produces 12 per cent of the questions and is still rising.
- Keep disaster management small but never empty: It has asked at least one question in every paper.
- Read science for applications: Know what each technology does and why it matters for India.
Where Current Affairs Matter Most in GS 3
Three subjects renew themselves every year. The economy changes through the budget and new schemes, science and technology through new missions and devices, and environment through climate talks and new frameworks. Agriculture and internal security change more slowly, so a settled base from textbooks and reports carries most of their questions.
The Study Library is organised by these subjects, and the other Mains papers feed this one: GS Paper 2 for institutions and Centre-state finance, GS Paper 4 for the ethics of administration, and the Essay paper for writing at length.
