A four-way comparison of UPSC’s most-debated optionals, built on UPSC’s own success-rate data, 42 years of History Optional previous year questions (1985–2026), and a question most comparisons never ask: how much of each paper could you have seen coming?
Quick Answer
No optional gives you a measurable selection advantage on its own, and History does not top the table on UPSC’s published success rates. Across CSE 2020–2022, History converted 4.9% of its Mains candidates into final selections (87 of 1,791), against 8.3% for PSIR, 8.4% for Sociology and 7.0% for Geography. The all-optional average was 8.1%. That gap is real, and you should go in knowing it. It mostly reflects who chooses History, not what History does to your marks.
On a different measure, though, History comes first: how far its previous year questions predict its next paper.
- History is the most static of the four. Its syllabus ends at 1991 in world history and in the early decades after independence for India. Nothing in it goes out of date between attempts.
- History repeats itself, literally. Our scan of the full archive found 33 near-identical question pairs, 17 of them effectively verbatim, from 1985 to 2025. The 2026 paper then reprinted two more (the Moplah question from 2018 and the Community Development question from 2019). About a quarter of 2026 Paper II belonged to question families a topic-wise reader had already met.
- PSIR is the least predictable of the four. Its Paper II tracks the twelve months before the exam.
- Sociology sits in between. It recycles thinkers and themes more than wording.
- Geography mixes static physical geography with a contemporary Paper II.
Choose History if you enjoy reading narrative and argument and have 4–5 months for a first pass. Choose it too if you would rather master a fixed body of questions than chase current affairs. Do not choose it because “everyone says it’s safe”: the data says it isn’t safe, it’s learnable. That is the case for preparing it through its PYQs. The History Optional PYQ Master Pack is built for exactly that.
The four optionals at a glance
Each optional is two papers of 250 marks, 500 marks in all: 28.6% of the 1,750 written marks. That is why this single choice matters more than almost any other in your preparation.
| History | PSIR | Sociology | Geography | |
|---|---|---|---|---|
| Paper I | Ancient and medieval India (to c. 1757) | Political theory, Indian political thought, Indian government and politics | Fundamentals of sociology (thinkers, methods, institutions) | Physical and human geography |
| Paper II | Modern India (Section A) and world history, 1750–1991 (Section B) | Comparative politics, IR theory, India and the world | Indian society: structure and change | Geography of India (includes contemporary issues) |
| Syllabus units | 51 clauses (24 + 27) | Four distinct bodies of knowledge | Ten units plus three parts | Physical, human, regional and Indian sections |
| Special component | 50-mark map question (Paper I, Q1) | None | Diagrams conventional | Maps and diagrams expected |
| Current-affairs dependence | Minimal | Very high in Paper II | Moderate (data, schemes, examples) | Moderate to high in Paper II |
| Mains candidates, CSE 2020–22 (3 yrs) | 1,791 | 5,812 | 4,168 | 3,661 |
| Success rate, CSE 2020–22 | 4.9% | 8.3% | 8.4% | 7.0% |
Candidate and success-rate figures are UPSC Annual Report (Table 5) data for CSE 2020, 2021 and 2022, pooled. See our Optional Subject Success Rate analysis for the full table.
What UPSC’s own numbers say (and don’t)
The headline
Across three recent cycles, History’s success rate was the lowest of any large optional:
| Exam year | Appeared (History) | Recommended | Rate | All-optional baseline |
|---|---|---|---|---|
| CSE 2020 | 581 | 24 | 4.1% | 8.1% |
| CSE 2021 | 574 | 25 | 4.4% | 8.4% |
| CSE 2022 | 636 | 38 | 6.0% | 8.0% |
| Three years | 1,791 | 87 | 4.9% | 8.1% |
Two things stand out. The rate rose in each year, from 4.1% to 6.0%. And History’s candidate pool is far smaller than folklore suggests, around 600 Mains candidates a year. That is 5.6% of all Mains candidates, against 18.1% for PSIR.
Why the headline misleads
A success rate is an end-to-end rate. A “recommended” History candidate cleared Essay, four GS papers, both optional papers and the interview. The optional is about a quarter of the final 2,025 marks, so the other three quarters do most of the work. The rate describes the pool that chose the subject (its degrees, attempt numbers and preparation years) far more reliably than it describes the subject.
The ceiling is not the problem either. History has produced an AIR 1 in CSE 2021 (Shruti Sharma), a Rank 9 in CSE 2023 (Nausheen) and some of the highest optional totals on record. Scores above 300 out of 500 have been reported more than once. What separates those scores from average ones is answer craft on the same syllabus: structure, historians and the map. That craft can be learned from past papers.
Myth-bust. “History has a 4.9% success rate, so I have a 4.9% chance.” No. The rate belongs to the historical pool, not to you. Switching optionals does not transfer another subject’s rate to you.
Syllabus size is the wrong yardstick
Almost every comparison ranks optionals by syllabus length, and History always loses: 51 clauses spanning the Palaeolithic to the collapse of the Soviet Union. But length only measures what you could be asked. What decides your score is what you actually are asked, and whether you can see it coming.
Three facts change the picture for History:
- The syllabus is closed. World history stops at 1991, and Indian history effectively stops at the early decades after independence. The question pool grows by about 46 questions a year, and none of the older questions go out of date.
- The weight is uneven, and knowable. Since the 2013 pattern change, Medieval India (750–1757) has drawn about 63% of Paper I’s topic-tagged questions, and Ancient India about 37%. In Paper II, Section A (Modern India) and Section B (World History) split almost exactly 50:50 (197 vs 196 questions, 2013–2026). You can plan to those proportions.
- Part of the paper is forced. Paper I Q1 is a 50-mark map, and each paper forces you to answer at least two questions from each section. Nobody can “skip” ancient India or world history. That is why reading the PYQs clause by clause beats reading the syllabus front to back.
PSIR’s printed syllabus looks shorter, but it hides four literatures: political philosophy, Indian politics, IR theory and contemporary diplomacy. Its Paper II syllabus hasn’t been revised in about two decades while the paper stays current. Sociology really is compact, which is its biggest advantage. Geography’s bulk sits in Paper I’s physical geography, which is static, and Paper II’s India section, which isn’t.
Static vs dynamic: how much of each paper depends on current affairs
This measure matters most for anyone taking more than one attempt. A static optional is an asset you build once. A dynamic optional is a subscription you keep paying.
| Optional | What changes between attempts | Maintenance cost |
|---|---|---|
| History | Almost nothing. New historiography occasionally (for example, recent debates on the eighteenth century), but no new events. | Lowest |
| Sociology | Examples, data, government schemes; theory is stable. Questions increasingly apply old thinkers to new contexts (digital identity, migration). | Low to moderate |
| Geography | Contemporary issues in Paper II; disasters, resources, regional planning data. | Moderate |
| PSIR | Paper II follows the world. The 2026 paper asked about NATO facing pressure from its own biggest member, the India–EU trade deal and US pressure on India–Russia ties. | Highest |
For History, this means every hour you spend is still useful next year. A repeater with History carries almost all of their first attempt forward. This is also why a bank of solved PYQs is worth more in History than in any other optional: model answers to 2008 questions are still model answers.
Repeat behaviour: can the past paper predict the next one?
History: literal repeats, and many more near-repeats
Using a token-similarity scan of every History Optional question from 1985 to 2025, we found 33 near-identical pairs, 17 of them effectively verbatim. Some propositions have been asked three times:
| Proposition | Clause | Years asked |
|---|---|---|
| Napoleon was “the child of the Revolution” yet reversed its aims | Origins of Modern Politics | 1986, 1992, 2004 |
| By the 1980s the Soviet system could not sustain superpower status | Disintegration of the USSR | 2007, 2013, 2017 |
| “Europe lost a mistress and gained a master” (Sedan, 1870) | Nation-State System | 1995, 2018 |
| The Industrial Revolution “put mobility in place of stability” | Industrialization | 1990, 2018 |
| The American War of Independence transformed Europe as well as America | Origins of Modern Politics | 1990, 2018 |
| Growth of Arab nationalism after WWI: a reaction to oil? | Liberation from Colonial Rule | 1989, 2016 |
| Moplah rebellion: anti-landlord and anti-foreign? | Indian Response to British Rule | 2018, 2026 |
| Community Development and Panchayati Raj for rural welfare | Economic Development and Political Change | 2019, 2026 |
Beyond word-for-word repeats, History recycles question families. These are the same claim reworded. The Carnatic Wars were asked in 2019, 2023, 2025 and 2026. The Orientalist–Anglicist controversy appeared in 1990, 2018 and 2026. The “safety valve” theory of the Congress’s founding came back in 2025 and 2026 back to back. On our analysis, a candidate who had worked the topic-wise archive had seen roughly a quarter of the 2026 Paper II before.
The gap between askings is long: our scan found a median of eight years, with some gaps of 28 years. So the full archive matters, not just the last decade.
The other three
- Sociology. In LotusArise’s count of 1,522 solved Sociology PYQs, 53 questions were asked in more than one year, mostly before 2013. Recent papers recycle thinkers and themes far more than wording. Marx, Weber, Durkheim and Merton come back every year, but framed afresh.
- PSIR. Paper I (political theory) repeats thinkers the way Sociology does. Paper II is written from the news. Its past papers teach you the form of questions far better than their content.
- Geography. Physical geography recycles concepts and models reliably. The India paper’s contemporary questions do not.
What this means: in History, working through the full archive of PYQs is preparation. In PSIR it is practice.
GS and Essay overlap
People claim overlap for every optional without showing it, so here is what we measured for History. We matched 82 GS Paper I history, culture and world-history questions (2013–2025) against the History Optional archive:
- 21 (26%) had a near-identical twin in the optional’s PYQs. For example, GS 2024 asked whether the First World War was fought for the balance of power. Optional 2015 had asked the same question almost word for word.
- 47 (57%) were thematically covered: an optional-prepared candidate would already have the answer’s content.
- 14 (17%) fell outside the optional (for example, Phule’s writings, indentured labour, Bhoodan, Chandella art).
The full match table, question by question, is in our companion article History Optional and GS Overlap.
| Optional | Where the overlap lands |
|---|---|
| History | GS I (modern, world, ancient and medieval, art and culture); Prelims history and culture; historical examples for the Essay |
| PSIR | GS II (polity, governance, IR), with strong Essay support |
| Sociology | GS I (society), GS II (social justice), GS IV and the Essay, spread across several papers |
| Geography | GS I (geography), GS III (environment, disaster management), Prelims geography and environment |
History’s overlap sits mostly in one GS paper, but that paper’s history section is large, and the optional covers most of it. It does not cover GS II or III.
The six-measure scorecard
Ratings are relative among these four, not absolute (●●● = strongest).
| Measure | History | PSIR | Sociology | Geography |
|---|---|---|---|---|
| Syllabus bulk (lower is better) | ● | ●● | ●●● | ●● |
| Static share (higher is better) | ●●● | ● | ●● | ●● |
| PYQ repeat value | ●●● | ● | ●● | ●● |
| GS / Essay overlap | ●● | ●●● | ●●● | ●● |
| Special component to master | Map (50 marks) | None | Diagrams | Maps and diagrams |
| Solved PYQs usable across attempts | ●●● (answers never go out of date) | ● (Paper II answers go out of date) | ●●● | ●● |
| Published success rate, 2020–22 | 4.9% | 8.3% | 8.4% | 7.0% |
Reading the scorecard: History costs the most time up front and the least afterwards. PSIR is the reverse. Sociology is the most balanced. Geography suits those who think spatially and like diagrams.
Who should pick History, and who shouldn’t
History suits you if
- You enjoy reading long narrative and argument. Most of the preparation is reading, and it has to feel like reading, not endurance.
- You want an optional that won’t go stale between attempts.
- You are willing to spend 4–5 months on a first pass (2–2.5 hours a day), then learn from past papers.
- You can argue a position. About a quarter of recent questions open with a quotation to be judged, not a topic to be described.
- You like the idea of 50 marks for map work that rewards steady drilling rather than insight.
History is a poor fit if
- You want the shortest syllabus. Sociology wins that easily.
- You need your optional to carry GS II (polity and IR). That is PSIR’s territory.
- You dislike memorising specifics (dates, sites, treaties, inscriptions). History answers without specifics score in the 10–13 band.
- You are choosing it only because it is “safe”. The published data doesn’t support that belief.
A tie-breaker that works
Open the 2026 History paper and a 2026 paper of your other option. Read both for twenty minutes. Which set of questions do you want to answer? Enjoying the subject is not a soft factor. It decides whether you will still be reading in month nine.
If you choose History: prepare it the way it’s examined
History’s biggest advantage is also its biggest trap. The archive is so rich that many aspirants read the books for a year and write their first real answer in July. Everything in this article points the other way:
- Read clause by clause, with the PYQs open. Every clause’s past questions show you which parts of the chapter the examiner actually uses. Start at the topic-wise PYQ archive.
- Prepare the families, not just the questions. When Carnatic Wars, safety valve or New Imperialism appears, you have met it before.
- Learn what a full-marks answer looks like before you try to write one. This is where most self-studiers lose a year, because the standard is invisible from the books.
The History Optional PYQ Master Pack gives you topic-wise model answers to History Optional PYQs from 1985 to 2025, arranged by syllabus clause, with map-section solutions, as a PDF and online. Because History’s syllabus is static and its questions repeat, a model answer written for a 1990 question is still the right model for its 2018 twin. No other optional’s solved papers keep their value that long.

Frequently Asked Questions
In one paragraph
On UPSC’s own figures, History is not the optional most likely to get you selected. Its 4.9% success rate is the lowest among the big humanities subjects, though rising. It is, however, the optional whose past papers best predict its future ones. Its syllabus is closed, its questions come back as families and sometimes word for word, and a model answer written years ago is still the right model today. PSIR asks you to keep up with the world; History asks you to master a fixed body of material. If that trade appeals to you, choose History and prepare it through its PYQs from day one.
