UPSC Syllabus 2026 – Complete Overview
The UPSC Civil Services Examination is one of the most competitive exams in the world. Every year, more than 10 lakh candidates apply for a few hundred vacancies. In a competition this intense, the difference between selection and near-miss often comes down to preparation quality, and preparation quality starts with knowing the syllabus.
The UPSC Syllabus 2026 has been officially released by the Union Public Service Commission as part of its annual notification. The syllabus covers all three stages of the exam: the Preliminary Examination, the Main Examination, and the Personality Test (Interview). It is available for download in both English and Hindi from the official website upsc.gov.in.
This guide provides a complete, section-by-section breakdown of the UPSC 2026 syllabus in English. It covers GS Paper 1 and CSAT for Prelims, all nine Mains papers with subject-wise details, the full list of 26 optional subjects, and practical guidance on how to use the syllabus effectively during preparation.

UPSC Exam 2026 – Three Stages at a Glance
The Civil Services Examination is divided into three stages. Each stage serves a distinct purpose in the selection process.
| Stage | Type | Total Marks | Counts in Merit? |
| Prelims | Objective MCQ | 400 (Paper 1 only) | No – screening only |
| Mains | Descriptive | 1750 | Yes |
| Interview | Personality Test | 275 | Yes |
| Final Merit | – | 2025 (Mains + Interview) | – |
Important: Your Prelims score does NOT affect your final rank. It is only a qualifying filter. The rank that appears in the final selection list is based entirely on Mains + Interview marks.
UPSC Prelims Syllabus 2026 – Paper 1 and CSAT
The Preliminary Examination is the first stage of the UPSC Civil Services process. It acts as a large-scale filter. More than 10 lakh aspirants appear, but only around 15,000 to 20,000 clear this stage to appear in Mains. Prelims is held on a single day, usually a Sunday in late May or June.
There are two papers. Both are objective-type (multiple choice). Both carry 200 marks each. Only Paper 1 counts for ranking. Paper 2 is qualifying.
| Paper | Marks | Duration | Nature |
| GS Paper 1 (General Studies) | 200 | 2 Hours | Merit-based |
| CSAT (Paper 2) | 200 | 2 Hours | Qualifying (33% min) |
Paper 1 – General Studies (200 Marks)
This is the paper that determines whether you qualify for Mains. It covers a wide range of topics that test general awareness and the ability to apply knowledge across domains. Questions are not deeply technical but require broad and consistent reading.
The complete topic list for Paper 1 is:
- Current Affairs: Events of national and international significance
- History: Indian History and the Indian National Movement
- Geography: Physical, social and economic geography of India and the World
- Polity and Governance: Indian Constitution, political system, Panchayati Raj, public policy, rights issues
- Economy: Sustainable development, poverty, demographics, social sector initiatives, inclusive growth
- Environment: Ecology, biodiversity, climate change – general level, non-specialist questions
- General Science: Basic principles of science relevant to everyday life and the civil services context
Paper 2 – CSAT (200 Marks, Qualifying)
CSAT stands for Civil Services Aptitude Test. It tests analytical and reasoning ability rather than factual knowledge. Minimum 33 percent is required to qualify. If you score below 33 percent in CSAT, your Paper 1 score is not evaluated at all.
CSAT covers:
- Comprehension of passages in English and Hindi
- Interpersonal skills and communication ability
- Logical reasoning and analytical thinking
- Decision-making and problem-solving
- General mental ability
- Basic numeracy – numbers, relationships, order of magnitude (Class 10 level)
- Data interpretation – charts, graphs, tables (Class 10 level)
Key point: Many aspirants underestimate CSAT. Questions on data interpretation and logical reasoning require specific practice. Treat it seriously from the beginning of preparation.
UPSC Mains Syllabus 2026 – All Nine Papers
The Mains Examination is where the real battle happens. This is a written examination with descriptive answers. It tests the depth of your understanding, your writing ability, and your analytical thinking. The 9 papers of Mains together carry 1750 marks that count in your final selection.
| Paper | Subject | Marks | Duration | Counted? |
| Paper A | Indian Language (Qualifying) | 300 | 3 Hours | No |
| Paper B | English (Qualifying) | 300 | 3 Hours | No |
| Paper I | Essay | 250 | 3 Hours | Yes |
| Paper II | GS 1 – Heritage, History, Geography, Society | 250 | 3 Hours | Yes |
| Paper III | GS 2 – Governance, Polity, International Relations | 250 | 3 Hours | Yes |
| Paper IV | GS 3 – Technology, Economy, Environment, Security | 250 | 3 Hours | Yes |
| Paper V | GS 4 – Ethics, Integrity and Aptitude | 250 | 3 Hours | Yes |
| Paper VI | Optional Subject – Paper 1 | 250 | 3 Hours | Yes |
| Paper VII | Optional Subject – Paper 2 | 250 | 3 Hours | Yes |
Paper I – Essay (250 Marks)
The Essay paper requires you to write two essays of approximately 1000 to 1200 words each. Topics can be philosophical, social, economic or governance-related. There is no fixed syllabus for this paper.
What UPSC evaluates here is the quality of thinking, the structure of the argument, clarity of expression, and a well-organised conclusion. The Essay paper is often neglected until the final months of preparation, which is a mistake. It rewards consistent practice over months, not cramming.
GS Paper 1 – Heritage, History, Geography and Society (250 Marks)
This paper covers a wide arc from ancient India to the present day. It rewards candidates who can connect historical events and social patterns to contemporary issues.
| Topic | What It Covers |
| Indian Heritage and Culture | Art forms, architecture, literature from ancient times to modern period |
| Modern Indian History | Major events, personalities and themes from 18th century to the present |
| Freedom Struggle | Phases of the independence movement, regional contributions, key figures |
| Post-Independence India | Integration and reorganisation of states, major policy shifts |
| World History | 18th century onwards – industrial revolution, world wars, colonialism, political philosophies |
| Indian Society | Caste, religion, regionalism, women’s issues, poverty, demographic change |
| Geography | Distribution of natural resources, geopolitical and economic geography of India and the world |
GS Paper 2 – Governance, Polity and International Relations (250 Marks)
This paper tests your knowledge of how India is governed and how India engages with the world. Many questions in this paper draw directly from current affairs.

| International Relations | Bilateral, regional and global agreements, India’s foreign policy |
| International Institutions | Structure, mandate and role of key global organisations |
GS Paper 3 – Economy, Environment, Technology and Security (250 Marks)

GS Paper 4 – Ethics, Integrity and Aptitude (250 Marks)
This is the one paper that cannot be prepared from any book alone. It evaluates your moral reasoning through theoretical questions and practical case studies. With 250 marks at stake, treating it as an afterthought is one of the most costly preparation errors aspirants make.
Strong answers here require clarity of values, honest reasoning, and the ability to apply ethical frameworks to real governance situations.

| Ethics and Human Interface | Essence of ethics, determinants of ethical behaviour, dimensions of ethics |

| Case Studies | Practical scenarios testing ethical decision-making in governance contexts |
Optional Subject – Papers VI and VII (500 Marks Combined)
The optional subject contributes 500 marks across two papers. It is the single largest contributor to your Mains score. Choosing wisely, based on genuine interest, availability of material, and scoring trends, can be decisive for your final rank.
The standard of questions is at Honours degree level for most subjects, and at postgraduate level for subjects like engineering and medicine.
UPSC Exam Pattern 2026 Hindi – Prelims, Mains and Interview Stages
The exam pattern is not the same as the syllabus. The pattern tells you how the exam is organised and how marks add up. Here is the full picture:
| Stage | Type | Total Marks | Counts in Final Merit? |
| Prelims | Objective (MCQ) | 400 (Paper 1 only) | No – only a screening filter |
| Mains | Descriptive (Written) | 1750 | Yes |
| Interview | Personality Test | 275 | Yes |
| Final Merit | – | 2025 (Mains + Interview) | – |
One thing many aspirants misunderstand: your Prelims marks do not affect your final rank. Prelims only decides who gets to sit for Mains. The rank you see in the final list is based entirely on your Mains score plus your Interview score.
This means the way you prepare for Prelims should be different from how you prepare for Mains. Prelims needs breadth and speed. Mains needs depth, writing practice, and time management across three-hour descriptive papers.
UPSC Optional Subject List 2026 – All 26 Subjects
Candidates must choose one optional subject from the list below. Both papers carry 250 marks each.
| Category | Optional Subjects Available |
| Sciences | Agriculture, Animal Husbandry and Veterinary Science, Anthropology, Botany, Chemistry, Medical Science, Physics, Statistics, Zoology |
| Engineering | Civil Engineering, Electrical Engineering, Mechanical Engineering |
| Social Sciences | Economics, Geography, History, Political Science & International Relations, Psychology, Public Administration, Sociology |
| Commerce and Law | Commerce and Accountancy, Law, Management, Mathematics, Philosophy, Geology |
| Languages (Literature) | Literature of any one of: Assamese, Bengali, Bodo, Dogri, Gujarati, Hindi, Kannada, Kashmiri, Konkani, Maithili, Malayalam, Manipuri, Marathi, Nepali, Odia, Punjabi, Sanskrit, Santhali, Sindhi, Tamil, Telugu, Urdu, or English |
Which Optional Works Well for Aspirants?
There is no universal best answer, but patterns from past selections offer useful guidance:
- Geography: Language-neutral map-based questions, strong material available, consistently popular among selections
- Public Administration: Directly relevant to civil services work, significant overlap with GS 2, good books available
- Sociology: Works well with structured notes, manageable scope, good scoring potential
- History: Extensive resources, significant overlap with GS 1, solid scoring subject for well-prepared candidates
- Political Science and International Relations: Heavy overlap with GS 2, rich current affairs connection
Whatever you choose, make sure you can access quality study material in your preferred language and that you have genuine interest in the subject. Forced preparation for 500 marks across a year is unsustainable.

UPSC Syllabus 2026 – Best Books and Study Resources
OOnce you have the syllabus, the next question is: what do you study? Here is a reliable set of resources for each stage of preparation.
| Resource | Type | Best Used For |
| NCERT Textbooks (Class 6–12) | Static Foundation | History, Geography, Polity, Economics, Science – non-negotiable starting point |
| Laxmikant – Indian Polity | Core Reference | Complete GS 2 polity section; available in English and Hindi |

On Using Coaching-Formatted Syllabi
Coaching institutes like Drishti IAS, Vision IAS and PW OnlyIAS publish their own formatted versions of the UPSC syllabus. These are useful as a starting guide because they often include reading lists and topic-wise explanations.
However, there is a real risk. Coaching-formatted syllabi sometimes include extra topics or commentary that goes beyond the strict UPSC scope. Following these without cross-referencing the official syllabus can lead to over-preparation in some areas and under-preparation in others.
The recommended approach: treat the official UPSC syllabus from upsc.gov.in as the final word on scope. Use coaching material to understand what each topic means, which subtopics matter, and which books cover it best. 250-word answers.
For guidance on how successful aspirants organise their notes, see our detailed post on Toppers Notes UPSC 2026. It covers handwritten notes strategy, subject-wise note-making, and how to avoid the trap of collecting notes without actually using them.
UPSC Syllabus 2026 Drishti IAS PDF – Official vs Coaching Material
Coaching institutes like Drishti IAS, Vision IAS, KGS IAS, and others publish their own versions of the UPSC syllabus. These are often formatted more neatly, come with attached reading lists, and are available in Hindi. They are genuinely useful as a starting guide.
But there is a real risk: coaching-formatted syllabi sometimes include extra topics or commentary that goes beyond the strict UPSC scope. Following these without cross-referencing the official syllabus can lead you to over-prepare in some areas and under-prepare in others.
How to Use Both Together
- Treat the official UPSC syllabus from upsc.gov.in as the final authority on scope
- Use coaching material to understand what each topic means, what subtopics to cover, and which books to use
- When in doubt about whether a topic is in the syllabus, go back to the official PDF, not a coaching summary
- For Hindi-medium students, specifically, Drishti IAS publishes strong Hindi material that aligns closely with the syllabus. It is one of the more reliable coaching resources for this medium
UPSC Optional Subject List Hindi – Complete List with Syllabus PDF
Choosing your optional subject is one of the most consequential decisions in your UPSC journey. It contributes 500 marks. Getting it right can make the difference between selection and being just outside the cutoff.
Here is the complete list of 26 optional subjects for UPSC Mains 2026:
| Category | Optional Subjects Available |

Which Optional Works Best for Hindi Medium Students?
There is no universal answer, but some patterns are clear from past selections:
- Geography: Strong Hindi material available. Map-based questions are language-neutral. Consistently popular among toppers
- Public Administration: Directly relevant to the civil services. Good Hindi books available. Overlaps significantly with GS 2
- Sociology: Abstract but manageable with a structured approach. Works well with Hindi-medium notes
- History: NCERTs provide a strong base. Hindi resources are extensive. Overlaps with GS 1
- Hindi Literature: For those with a strong humanities background and comfort with literary analysis, this can be a high-scoring choice
Whatever you choose, make sure you can access quality material in your medium of writing, and that you have a genuine interest in the subject. Forced preparation for 500 marks is hard to sustain across a year of preparation.
UPSC Syllabus 2026 – How to Actually Use It During Preparation
Having the syllabus and using it effectively are two different things. Here are the habits that experienced aspirants develop.
Step 1: Read the Entire Syllabus Before Buying a Single Book
Spend two to three days reading the complete official syllabus from front to back. Mark every topic you are unfamiliar with. This gives you a personalised gap analysis, which is far more useful than any generic study plan someone else has made.
Step 2: Map Each Syllabus Topic to a Study Source
Take a notebook. Write down each syllabus topic and note beside it which book, resource or chapter covers it. This mapping exercise forces you to check whether you actually have the right material, rather than assuming you are covered.
Step 3: Treat Prelims and Mains as Different Exams
Prelims needs breadth and speed across many topics. Mains needs depth, structured thinking and the ability to write 250-word analytical answers under time pressure. Many aspirants fall short at Mains because they prepared for both stages the same way.
Step 4: Start Answer Writing in the First Month
Do not wait until the syllabus is fully covered before starting answer writing. Start with short 150-word answers from month one. Gradually increase to full-length 250-word answers. Get your answers reviewed where possible.
Step 5: Map Every News Article to a Syllabus Topic
Every time you read a newspaper article, ask yourself: which part of the UPSC syllabus does this belong to? This habit converts passive reading into directed revision and keeps your notes organised by topic rather than by date.
Step 6: Learn From Actual Selections
Reading about the strategies of candidates who have cleared the exam is one of the most practical things you can do early in your preparation. Our detailed post on UPSC Hindi Medium Toppers List on sdreserchworld.in covers real names, ranks, optional subject choices and preparation strategies from candidates who cleared in Hindi medium.
Step 7: Plan State Services Alongside UPSC If Relevant
Many serious aspirants prepare for state services simultaneously, especially in the early years. The syllabi overlap significantly with UPSC. For UP-based aspirants, our guide on UPPSC PCS Preparation Strategy 2026 on sdreserchworld.in covers how to balance both preparations without losing focus on either.
UPSC Personality Test 2026 – Interview Stage
The Personality Test, commonly called the UPSC Interview, carries 275 marks. It is the final stage of the selection process and is held in UPSC Bhavan, New Delhi.
There is no written syllabus for the Interview. The board evaluates the candidate’s personality, not their knowledge of specific facts. What is tested includes:
- Mental alertness and clarity of thought
- Critical powers of assimilation and ability to weigh evidence
- Depth and breadth of outlook
- Social traits and interest in current affairs
- Intellectual and moral integrity
Candidates should expect questions on their work experience or academic background, their optional subject, their home state and district, current affairs, and ethical dilemmas in governance. The board may also ask about interests and hobbies mentioned in the Detailed Application Form (DAF).
The Interview is not an oral exam on the syllabus. It is a structured conversation about you, your thinking, and your readiness to serve as a civil servant. Authenticity matters more than rehearsed answers.
