UPSC Prelims GS Paper I syllabus

The notification gives the marks and duration for General Studies Paper I: 200 marks in two hours. UPSC also publishes its official question papers, which are the source to check for question counts and marks per question in a particular cycle. The notification does not promise a topic-wise distribution of questions. See the official UPSC examination page for the notification and both question papers.

What UPSC does state precisely is the penalty. One third of the marks assigned to a question is deducted for a wrong answer. A question left blank costs nothing, and giving more than one answer counts as wrong even if one of them is correct.

The syllabus below is reproduced in the Commission’s own wording, including the sub-clauses that most summaries drop. Browse the available UPSC Prelims practice papers.

Syllabus by section

GS Paper I has no sections. It is a single undivided paper covering seven subject headings, which is why this page carries the whole syllabus rather than linking out to section pages.

General Studies Paper II200Two hoursQualifying only, at 33 per cent

The negative marking rule, stated exactly as the notification does, has three parts. One third of the marks assigned to that question is deducted for a wrong answer. Giving more than one answer is treated as a wrong answer and carries the same penalty, even if one of the answers given is correct. A question left blank carries no penalty.

Paper II is what candidates call the CSAT. The notification does not use that term and calls it General Studies Paper II throughout. Thirty three per cent of 200 marks is 66.67 marks, and failing to reach it ends the attempt regardless of how well Paper I went.

The penalty is one third of the marks assigned to the question. Use the instructions on the official question paper to confirm the question value and calculate that penalty; the notification's total marks alone are not a substitute for the paper instructions.

The official syllabus

These are the seven headings as the notification words them, including the qualifiers that summaries usually cut.

  • Current events of national and international importance
  • History of India and Indian National Movement
  • Indian and World Geography: physical, social and economic geography of India and the world
  • Indian Polity and Governance: Constitution, political system, Panchayati Raj, public policy, rights issues and so on
  • Economic and Social Development: sustainable development, poverty, inclusion, demographics, social sector initiatives and so on
  • General issues on environmental ecology, biodiversity and climate change, that do not require subject specialisation
  • General Science

Two qualifiers are worth keeping. The environment heading carries the explicit limit that the questions do not require subject specialisation, which caps the depth candidates need. And four of the seven headings carry sub-clauses after a dash, which are part of the syllabus rather than examples bolted on afterwards.

General Studies Paper II

The second paper is qualifying, but it is qualifying in the sense that failing it ends the attempt. Its syllabus is set out in the notification as follows.

  • Comprehension
  • Interpersonal skills including communication skills
  • Logical reasoning and analytical ability
  • Decision making and problem solving
  • General mental ability
  • Basic numeracy, covering numbers and their relations and orders of magnitude, at class X level
  • Data interpretation, covering charts, graphs, tables and data sufficiency, at class X level

The class X level qualifier applies to basic numeracy and to data interpretation and is stated in the notification. It is the clearest statement of depth anywhere in the Prelims syllabus.

How the pattern has changed

Nothing material has changed in recent cycles. The two paper structure, the 200 marks and two hours per paper, the one third penalty, the 33 per cent qualifying threshold on Paper II and the attempt limits are all as they have been.

What moves from year to year is the vacancy count and the examination date, neither of which affects preparation.

One framing point worth correcting, because it recurs in preparation material. UPSC describes the Civil Services Examination as two stages rather than three. The Personality Test is part of the Main Examination stage rather than a separate third stage.

What is not in the syllabus

  • No guaranteed topic-wise question distribution
  • No fixed topic-wise weightage in the syllabus notification
  • No sectional division within GS Paper I. It is a single undivided paper
  • No subject specialisation in the environment heading, which the notification states explicitly
  • No optional subject at the Preliminary stage
  • No descriptive component. Both papers are objective
  • No carry forward of Prelims marks into the final merit

How to spend the time

Work out your own guessing threshold from the penalty rather than from a rule of thumb. At one third of the question value, breaking even requires one correct answer for every three wrong. Narrowing four options to two makes an attempt clearly worth taking and a blind guess across four does not.

Do not neglect Paper II because it is qualifying. Thirty three per cent is a low bar until the paper is harder than expected, and a candidate who clears Paper I comfortably and misses Paper II has lost the year.

Current events sits first in the syllabus for a reason. It is the heading that cannot be built in the final months, and it feeds into polity, economy and environment questions rather than standing apart from them.

Take the environment qualifier at face value. Questions on ecology, biodiversity and climate change do not require subject specialisation, so reading at that depth is the correct depth. Browse the available UPSC Prelims practice papers.

Common mistakes

  • Treating a coaching topic-weightage estimate as a fixed official distribution
  • Guessing blind across four options at a one third penalty
  • Giving more than one answer, which is treated as wrong even when one of them is correct
  • Leaving Paper II unprepared because it is qualifying
  • Studying environment and ecology at specialist depth, which the notification rules out
  • Expecting Prelims marks to count towards the final merit, when they do not
  • Describing the examination as three stages, when UPSC treats the Personality Test as part of the Main Examination
  • Dropping the sub-clauses from the syllabus headings, which are part of the syllabus

UPSC Prelims against a State PSC prelims

Most State Public Service Commission prelims copy the architecture: two objective papers, a General Studies paper that carries the merit and a second aptitude paper qualifying at 33 per cent, with the prelims acting purely as a screen whose marks are discarded afterwards.

FeatureUPSC PrelimsA State PSC prelims
Conducting bodyUnion Public Service CommissionThat state’s Public Service Commission
StructureTwo objective papersUsually two objective papers
Merit paperGeneral Studies Paper IUsually the General Studies paper

International contentCurrent events and world geographyUsually lighter

The substantive difference is scope. A State PSC paper gives real weight to that state’s own geography, history, polity and current affairs, none of which appears in the UPSC syllabus, while UPSC carries international current events and world geography that a state paper treats lightly.

Frequently asked questions

How many questions are in UPSC Prelims GS Paper I?

Check the official question paper for the relevant cycle to confirm its question count and marks per question. The syllabus notification specifies 200 marks and two hours; it does not specify topic-wise question counts.

What is the negative marking in UPSC Prelims?

One third of the marks assigned to that question is deducted for a wrong answer. A question left blank carries no penalty.

What happens if I mark two answers?

It is treated as a wrong answer and attracts the same penalty, even if one of the answers given happens to be correct.

Do Prelims marks count towards the final merit?

No. The Preliminary Examination is a screening test and its marks are not counted in determining the final order of merit.

Is GS Paper II compulsory?

Yes. It is qualifying rather than merit bearing, with minimum qualifying marks fixed at 33 per cent, and failing it ends the attempt.

Does UPSC call Paper II the CSAT?

No. The notification calls it General Studies Paper II throughout. CSAT is conventional usage.

How deep does the environment syllabus go?

The notification limits it to general issues that do not require subject specialisation.

How many attempts do I get?

Six for general and EWS candidates, nine for OBC candidates and unlimited for SC and ST candidates. Candidates with a benchmark disability get nine in the general, EWS and OBC categories and unlimited in the SC and ST categories.

Does appearing in one paper count as an attempt?

Yes. Appearing in any one paper of the Preliminary Examination counts as an attempt, even if candidature is later cancelled.

What is the age limit?

Twenty one to below 32 as on the date notified for that cycle, with relaxations of five years for SC and ST candidates, three years for OBC candidates and ten years for candidates with a benchmark disability, among others.

How many candidates are called for the Main Examination?

About twelve to thirteen times the number of vacancies to be filled that year.

Is the Civil Services Examination two stages or three?

UPSC describes it as two successive stages. The Personality Test forms part of the Main Examination stage rather than a separate third stage.
