Exam pattern: OCS Mains GS Paper 1 at a glance

GS Paper 1 is a 250-mark, three-hour paper with 17 questions split into two groups, and the split decides how you should manage your time.

Time planning tip: Spend about 2 hours 10 minutes on Group A (roughly 13 minutes per answer) and about 50 minutes on Group B (roughly 10 minutes per answer). Group B carries the higher marks per question and has no choice, so never leave it for the last five minutes.

The paper is bilingual, with every question printed in English and Odia, so you can write in the language you are most comfortable with.

Below is the English text of all 17 questions. Keeping the text on the page also helps search engines find this article, because a PDF alone cannot be read as easily.

Group A analysis: Questions 1 to 12 (15 marks, 250 words each)

Group A was a mix of Odisha-specific history and society, Indian history, and physical and human geography; most questions were direct and answerable if your basics were clear. Below, each question is explained in plain words, with the points a high-scoring answer should include.

Q1. Literature and tribal traditions in Odisha's socio-economic development

Topic: Odisha culture and society | Difficulty: Moderate

The phrase "how far" asks you to judge the extent of influence, so give both the strong effects and the limits.

• Literature: Sarala Das's Odia Mahabharata (15th century), the Panchasakha poets of the 16th century, Fakir Mohan Senapati, Radhanath Ray and Gangadhar Meher. Show how literature built a shared language identity, supported the Odia language movement and spread social reform ideas.

• Tribal traditions: community forest management, sacred groves, weekly haats and barter, traditional herbal medicine, and handicrafts such as Dokra metal casting and sabai grass work that support livelihoods.

• Integration: the Jagannath cult, whose Daitapati servitors trace their origin to the Sabara tribe, is the best example of tribal and mainstream traditions merging.

• Limits: displacement, loss of forest rights and language decline show that influence has not been equal for all.

Q2. Non-cooperation movement and the social base of Odia nationalism

Topic: Modern Odisha history | Difficulty: Moderate to difficult

Start with the background: the Utkal Union Conference (1903) under Madhusudan Das had built an elite, middle-class Odia identity. Then show how the Non-cooperation movement (1920 to 1922) widened it.

• Gopabandhu Das and the Utkal Provincial Congress Committee brought Odisha into the Congress fold.

• Gandhi's visit to Odisha in 1921 carried the message to ordinary people.

• Students, peasants, women and tribal communities joined through boycotts, the charkha and national schools.

• Link the story to the ultimate goal: the creation of a separate Odisha Province on 1 April 1936.

Q3. Indian art forms in the Gupta period

Topic: Indian art and culture | Difficulty: Easy

This was the most scoring question for students who had read NCERT-level art and culture. Cover each art form with an example:

• Architecture: early structural temples such as the Dashavatara temple at Deogarh and the brick temple at Bhitargaon.

• Sculpture: the Sarnath and Mathura schools of Buddha images, and the Udayagiri Varaha panel.

• Painting: the Ajanta murals, with Caves 16 and 17 associated with this era.

• Metal craft: the Delhi Iron Pillar of Chandragupta II and the copper Buddha of Sultanganj.

• Coinage: gold coins showing kings in artistic poses, such as Samudragupta playing the veena.

Q4. Foundation of the Indian National Congress and the Safety Valve theory

Topic: Modern Indian history | Difficulty: Easy to moderate

"Critically examine" needs both sides of the debate.

• The theory: A.O. Hume, a retired British official, founded the Congress in 1885 with the blessing of Viceroy Dufferin, so that Indian anger could find a peaceful outlet. Lala Lajpat Rai popularised this view.

• The counter-view: Moderate leaders such as Dadabhai Naoroji and W.C. Bonnerjee used the platform to build political awareness, criticise economic exploitation and push for representation; the Congress soon moved beyond the aims of its British founder.

• Your conclusion: the Safety Valve explains the early British support, but the Congress grew into a national platform because Indians used it for their own purposes.

Q5. Surendra Sai and the Revolt of 1857

Topic: Odisha freedom struggle | Difficulty: Moderate

The statement claims that Surendra Sai linked Odisha's resistance with the Great Revolt. Test it with evidence.

• In favour: Sambalpur was annexed in 1849 under the Doctrine of Lapse; Sai fought for his rights for decades and was jailed at Hazaribagh, from where he was freed in July 1857 during the revolt there. He then led guerrilla warfare with the support of Gond, Binjhal and other local communities and surrendered only in 1862.

• Against: his struggle began long before 1857, it was regional and dynastic in origin, and it had no organised link with the main centres of revolt.

• Conclusion: he did connect Odisha to 1857, but through his own long local struggle rather than a planned all-India plan.

Q6. The Gajapati rulers: conquerors who could not consolidate

Topic: Medieval Odisha | Difficulty: Moderate

• Conquests: Kapilendra Deva (founder, 1435), Purushottama Deva and Prataprudra Deva extended the empire from the Ganga region in the north to the Kaveri region in the south.

• Why consolidation failed: constant wars on several fronts with the Bahmani successors, Bengal and Vijayanagara; the loss of Udayagiri and Kondavidu to Krishnadevaraya in 1514 to 1515; weak administration in distant provinces; rebellious feudal chiefs; and disputes over succession.

• End of the dynasty: the usurpation by Govinda Vidyadhara in 1541 and the final fall to the Afghan power of Bengal in 1568.

Q7. Environmental adaptations of the Kondh community

Topic: Odisha tribes and environment | Difficulty: Moderate

• Hill-slope farming, mixed cropping of millets, pulses and turmeric, and rotational (podu) cultivation fitted to steep terrain.

• Orchards of jackfruit, mango and pineapple among the Dongria Kondh; seed saving and traditional farming knowledge.

• Worship of nature, including the earth deity Dharni Penu, and sacred hills and groves that protect forests.

• Collection of minor forest produce and herbal medicine from nearby forests.

• Mention Niyamgiri and the 2013 Supreme Court direction that gave Gram Sabhas a decisive role, to show the link between culture and environment.

Q8. Anthropogenic climate change and ocean acidification

Topic: Environment and geography | Difficulty: Easy

• Human activities: burning of fossil fuels, deforestation, methane from agriculture and livestock, industrial gases, and urban heat. Explain how each increases greenhouse gases and warming.

• Effects: rising temperatures, sea-level rise, changing monsoon patterns, and more extreme events such as cyclones, floods and heat waves.

• Ocean acidification: oceans absorb a large share of the carbon dioxide we emit. It reacts with seawater to form carbonic acid, which lowers pH and reduces the carbonate that corals, molluscs and shell-forming plankton need. Ocean pH has fallen by about 0.1 since the industrial era.

• Other causes: nutrient runoff and eutrophication, and acid deposition from sulphur and nitrogen oxides.

Q9. The Circum-Pacific region: instability, energy and minerals

Topic: World geography | Difficulty: Moderate

• Instability: the Ring of Fire, about 40,000 km long, follows subduction zones where the Pacific Plate meets neighbouring plates. It holds roughly three-quarters of the world's active volcanoes and produces about 90 per cent of its earthquakes. Name the trenches (Mariana, Peru-Chile, Japan) and island arcs.

• Energy: oil and gas in Alaska, Indonesia, Sakhalin and the Gulf of Mexico side; coal in Australia, Indonesia and China; geothermal power in Japan, the Philippines, Indonesia and New Zealand.

• Minerals: copper in Chile and Peru, tin in Southeast Asia, nickel in Indonesia and the Philippines, gold and silver along the Andes and Rockies, and lithium in Chile.

• A simple outline map earns extra credit.

Q10. Landslides in the Eastern Ghats and Odisha

Topic: Geography and disaster management | Difficulty: Moderate to difficult

• Geological causes: ancient, folded and faulted rocks such as khondalite, charnockite and gneiss; deep weathering; steep escarpments; joints and fractures that weaken slopes.

• Development pressure: road cutting, mining, quarrying, loss of forest cover, and settlement on slopes in districts such as Koraput, Rayagada, Gajapati and Kandhamal.

• Climate triggers: intense rainfall bursts and cyclone-linked heavy rain saturate loose soil; climate change is making extreme rainfall more frequent.

• Solutions: landslide susceptibility mapping, slope engineering, afforestation, early warning, and regulated construction.

Q11. Urbanisation in India: trends and issues

Topic: Indian society and geography | Difficulty: Easy

• Trends: India was about 31 per cent urban in Census 2011; the number of census towns rose sharply from 1,362 in 2001 to 3,894 in 2011; growth of million-plus cities (53 in 2011); peri-urban sprawl; and rising migration.

• Issues: housing shortage and slums (about 65 million slum residents in 2011), traffic, water and sanitation gaps, solid waste, air pollution, urban floods and heat, and weak finances of urban local bodies despite the 74th Constitutional Amendment.

• Responses: Smart Cities Mission, AMRUT, Swachh Bharat Mission (Urban) and PM Awas Yojana (Urban).

Q12. PVTGs in India and Odisha

Topic: Tribal society | Difficulty: Easy to moderate

• Background: the Dhebar Commission (1960 to 1961) identified the least-developed tribes; the category was later named Primitive Tribal Groups and renamed Particularly Vulnerable Tribal Groups in 2006.

• Criteria: pre-agricultural level of technology, a declining or stagnant population, very low literacy, and a subsistence economy.

• Numbers: 75 PVTGs across 18 states and the Andaman and Nicobar Islands; Odisha has the highest number, 13.

• Odisha profiles: Dongria Kondh (Niyamgiri hills), Bonda and Didayi (Malkangiri), Juang (Keonjhar), Lanjia Saura (Rayagada and Gajapati), Kutia Kondh (Kandhamal), Birhor and Mankirdia (nomadic, rope making) and Lodha (Mayurbhanj).

• Policy: mention the PM-JANMAN mission launched in 2023 for housing, roads, health and education in PVTG habitations.

Group B analysis: Questions 13 to 17 (20 marks, 300 words each, all compulsory)

Group B was the real test: three of the five questions came from news of the last year (Konark, Great Nicobar and the transgender law), so students who followed current affairs had a clear edge. Because all five are compulsory, a gap in current affairs costs marks you cannot dodge.

Q13. Konark Sun Temple: damage, conservation and sand removal

Topic: Odisha art, architecture and current affairs | Difficulty: Moderate

The question has three parts, so give each roughly equal space: causes of damage, past conservation, and the present ASI work.

• Background: built in the 13th century by Narasimhadeva I of the Eastern Ganga dynasty, dedicated to the Sun God, designed as a giant chariot, and recognised as a UNESCO World Heritage Site in 1984.

• Causes of damage: the weight of the massive tower on a coastal, sandy foundation; salt-laden sea winds that weather the stone; corrosion of iron beams; the collapse of the main tower over time; neglect after the shrine lost worship; and the 1568 invasion by Kalapahad, along with later removal of sculptures and the Aruna pillar to Puri.

• Past conservation: in 1900 to 1903 the British authorities cleared the ruins and filled the Jagamohana (assembly hall) with sand, sealing its four doors with a parallel wall, to stop its collapse. The ASI took charge in 1939 and added plantations as windbreaks against the coastal winds.

• Steps now: the ASI took a decision at a national conference in 2020, held a Bhumi Pujan in 2021, took samples for analysis by IIT Madras, and in 2026 began a carefully monitored operation by opening a narrow passage through the western wall for manual sand removal, with structural strengthening planned. Experts say the old sand has settled and now stresses the walls, so removal should add to the temple's life. Opening the Jagamohana to visitors is the intended outcome.

• Conclusion: stress the balance between safety and heritage ethics, and mention continuous monitoring.

Q14. The States Reorganisation Commission (1953) and linguistic regionalism

Topic: Polity and post-independence India | Difficulty: Moderate

• Background: the death of Potti Sriramulu after a fast in 1952 and the creation of Andhra in 1953 forced the Centre to appoint the commission under Fazl Ali, with K.M. Panikkar and H.N. Kunzru as members.

• Findings (1955): it accepted language as an important basis for states but not the only one, giving weight also to national unity and security, financial viability and planning needs. It ended the Part A, B and C classification and led to the States Reorganisation Act, 1956, with 14 states and 6 Union Territories.

• Successes: it reduced a major source of unrest, helped regional languages and cultures flourish, and showed that India could accommodate diversity within a federal unity.

• Criticisms: delay fuelled agitations (for example, over Bombay); some demands remained unmet, leading to Maharashtra and Gujarat (1960) and Punjab (1966); and it did not fully resolve border and river disputes.

• Odisha link: Odisha, formed as a linguistic province in 1936, was an early precedent for this principle.

Q15. Environmental and social vulnerabilities of coastal Odisha

Topic: Odisha geography, disaster and society | Difficulty: Moderate

Divide your answer into environmental and social vulnerabilities, then end with the response.

• Environmental: a coastline of about 480 km in the path of Bay of Bengal cyclones (the 1999 Super Cyclone, Phailin 2013, Fani 2019); storm surge and floods in the Mahanadi, Baitarani and Brahmani deltas; coastal erosion and sea-level rise (the Satabhaya village in Kendrapara is a well-known case); saline water entering farmland and groundwater; and the loss of mangroves such as those at Bhitarkanika.

• Social: dependence on fishing, farming and a few livelihoods; poverty and weak housing; conflict between traditional fishers and mechanised trawlers; migration of men that leaves women to carry the burden; limited health and education access; and displacement of communities.

• Response: the Odisha State Disaster Management Authority, multi-purpose cyclone shelters, early warning and mass evacuation, mangrove restoration and livelihood diversification.

• Way forward: climate-resilient housing, community-based adaptation, insurance, and alternative incomes.

Q16. Great Nicobar Island, the Great Nicobar Project and China's Malacca Dilemma

Topic: Geography, international relations and current affairs | Difficulty: Moderate to difficult

• Geostrategic importance: Great Nicobar is India's southernmost island, close to the western entrance of the Strait of Malacca, one of the busiest sea lanes in the world, near the Six Degree Channel. It lets India watch traffic between the Indian Ocean and the Pacific.

• The project: a large development plan valued at roughly US$9 billion, centred on an international container transhipment port, along with an airport, a township and a power plant; it was cleared in early 2026 after environmental review. The aims are to stop Indian cargo from being transhipped at foreign ports and to strengthen maritime security.

• The Malacca Dilemma: a phrase linked to Hu Jintao in 2003, describing China's dependence on this narrow strait for oil and trade; reports say over 70 per cent of China's oil passes through it. Analysts argue that an Indian base nearby could increase surveillance and leverage over this route in a crisis, which is why Chinese strategists have reacted to it. China has tried to reduce the risk through the China-Pakistan and China-Myanmar economic corridors and pipelines.

• Balance with concerns: the project has been criticised for the loss of forest cover, harm to the Shompen and Nicobarese communities, and risks in a high-seismic, tsunami-prone zone. A balanced answer notes the supporters' strategic case and the critics' ecological and tribal rights case.

Q17. Transgender law: end of self-perceived identity

Topic: Society, law and current affairs | Difficulty: Difficult (very recent and sensitive)

The question refers to the Transgender Persons (Protection of Rights) Amendment Act, 2026. A strong answer stays neutral, factual and constitutional.

• Background: the NALSA judgment (2014) recognised self-identification of gender as part of dignity and liberty, and the 2019 Act's Section 4(2) gave every transgender person the right to self-perceived gender identity.

• What changed: the 2026 amendment removes the right to self-perceived gender identity and narrows the definition of a transgender person. A District Magistrate now considers a medical board's recommendation before issuing the certificate of identity. It also states that persons of different sexual orientations or self-perceived sexual identities are not covered. The Supreme Court has issued notice on petitions challenging the Act.

• Government's reasoning: clarity on who benefits from welfare measures and prevention of misuse.

• Impact: socio-economic (access to certificates, and through them to schemes, jobs, education and healthcare, along with delays and gatekeeping); psychological (dignity, stress and stigma, and worries about medical examination); and constitutional (Articles 14, 15, 19 and 21).

• Way forward: protect dignity, set clear and respectful procedures, keep welfare access simple, and await the court's decision.

Subject-wise weightage and overall difficulty level

Overall, the paper was of moderate difficulty: history and culture questions were the largest block (7 of 17), and about half the paper had an Odisha angle.

What this tells us:

• Odisha knowledge is non-negotiable. Nine of the 17 questions carried an Odisha component, so a candidate who studies only national topics will lose a lot of marks.

• Current affairs now decide Group B. Konark, Great Nicobar and the transgender law were all live issues in 2026, and each was worth 20 marks.

• Questions were two-part. Q8, Q9, Q10, Q11, Q13 and Q16 asked for more than one thing, so missing a part cost marks.

• Static basics still score. Q3, Q4, Q8 and Q11 were answerable from standard textbooks.

This is our judgement of the paper, and your own experience may differ.

How to prepare for OCS Mains GS Paper 1: a simple strategy

The best preparation for this paper is a mix of strong Odisha basics, regular current affairs and daily answer writing. Follow these steps.

1. Build the Odisha base first. Read Odisha history from the Kalinga era to the 1936 formation of the province, plus culture (temples, festivals, art forms), tribes, geography, rivers, disasters and economy. Make one-page notes for each topic.

2. Link static to current. Q13 shows the pattern: a heritage site (static) combined with the ASI's latest work (current). For every monument, tribe, scheme or place in your notes, add the latest news beside it.

3. Follow a 12-month current affairs cycle. Read a good newspaper daily and prepare short notes on national issues and Odisha issues separately.

4. Answer in a simple structure. Use a short introduction, 3 to 5 clear headings with points and examples, and a balanced conclusion. For "critically examine" and "how far" questions, always show both sides.

5. Practise within the word limit. Write 250-word answers in about 13 minutes and 300-word answers in about 10 minutes. Time yourself.

6. Use maps and diagrams. Q9 (Circum-Pacific), Q10 (landslides), Q15 (coastal Odisha) and Q16 (Great Nicobar) all gain from a quick sketch.

7. Revise multi-part questions. Underline each part of the question before writing and tick them off at the end.

8. Take mock tests and get feedback. Writing alone is not enough; an experienced mentor's feedback shows what examiners reward.

If you wrote this paper today, avoid discussing it endlessly with friends. Take a short rest and move on to the next paper with a fresh mind.
