About the UPSC CSE exam

Recruitment to the All-India Services and Central Civil Services (Group A & B) — including the IAS, IPS and IFS.

What is the UPSC Civil Services Examination?

The Civil Services Examination (CSE), conducted every year by the Union Public Service Commission, is India's most prestigious and competitive recruitment examination. It selects officers for the All-India Services and the Central Civil Services — most notably the Indian Administrative Service (IAS), Indian Police Service (IPS) and Indian Foreign Service (IFS).

The CSE is a three-stage process: the Preliminary examination (objective, screening), the Main examination (nine descriptive papers) and a Personality Test (interview). Every year around a million candidates apply, of whom only a few thousand clear the Prelims and roughly a thousand are finally recommended — making a disciplined, exam-accurate practice routine essential from the very first stage.

Why the Prelims is a game of accuracy and elimination

The Prelims General Studies Paper I has 100 questions for 200 marks in two hours, with a one-third negative marking. Because only GS Paper I counts towards the cut-off and the paper spans polity, history, geography, economy, environment, science and current affairs, breadth of coverage matters more than depth in any single area.

The negative marking makes intelligent guessing and option elimination a core skill: clearing the cut-off is about maximising net score, not raw attempts. Practising full-length mocks that reproduce the real question mix, the OMR interface and the two-hour clock is the surest way to build the calibrated risk-taking that separates candidates who clear the Prelims from those who narrowly miss.

UPSC CSE eligibility & exam pattern

Check whether you meet the UPSC CSE eligibility criteria and understand exactly how the paper is structured and marked before you plan your preparation.

Eligibility criteria

Qualifying degree
A Bachelor's degree in any discipline from a recognised university; final-year students may appear for the Prelims.
Age limit
21 to 32 years for the General category as on 1 August of the exam year, with relaxations for reserved categories.
Number of attempts
6 attempts for General, 9 for OBC, and unlimited (up to the age limit) for SC/ST candidates.
Nationality
For the IAS and IPS a candidate must be a citizen of India; other services allow certain other categories per the rules.
Reservation
UPSC follows Government of India norms for SC, ST, OBC, EWS and PwBD candidates.
Physical standards
Certain services (e.g. IPS) have additional physical and medical standards to be met at a later stage.

Exam pattern & marking

SubjectQuestionsMarks
GS Paper ICounts for merit — decides the Prelims cut-off100200
CSAT (Paper II)Qualifying only — must score 33% (66 marks)80200
Total180200

In both papers, each correct answer earns +2 (GS-I) and marks are deducted by one-third of the allotted marks for every wrong answer (about −0.66 in GS-I). Unattempted questions carry no penalty. Only GS Paper I is counted for the Prelims merit list; CSAT (Paper II) is merely qualifying, requiring at least 33%.

Duration: GS Paper I — 2 hours; CSAT (Paper II) — 2 hours (qualifying).

How to prepare for UPSC CSE

A proven, focused UPSC CSE preparation method — from building strong fundamentals to peaking with full-length mocks.

  1. 1

    Build a strong NCERT foundation

    Read the NCERT textbooks (classes 6–12) for history, geography, polity and economy before moving to standard reference books. They give you the conceptual base on which every advanced topic and current-affairs linkage rests.

  2. 2

    Make current affairs a daily habit

    Follow a good newspaper and a monthly compilation every single day, and connect each item back to the static syllabus — a large and growing share of Prelims questions are current-affairs driven.

  3. 3

    Revise relentlessly with notes

    The syllabus is vast, so success depends on revision, not just first-time reading. Maintain crisp, consolidated notes and revise them in spaced cycles so that what you study in June is still fresh in May.

  4. 4

    Master negative marking with mocks

    Take full-length Prelims mocks under the real two-hour, OMR-style setting, and after each one study which guesses paid off and which cost you — this calibrates how many risks to take to maximise your net score.

  5. 5

    Don't ignore CSAT

    CSAT (Paper II) is only qualifying, but every year candidates fail to clear its 33% bar. If comprehension or basic maths is a weak area, drill it steadily rather than assuming you'll clear it comfortably.

  6. 6

    Integrate Prelims and Mains preparation

    Prepare topics with both stages in mind from the start. Answer-writing practice for Mains deepens the very understanding that helps you eliminate tricky options in the Prelims, so treat the two as one continuous effort.

UPSC CSE — frequently asked questions

Quick, reliable answers to the questions UPSC CSE aspirants ask most.

What is the UPSC Prelims exam pattern and marking scheme?

The Prelims has two papers of 200 marks each, taken on the same day. General Studies Paper I has 100 objective questions and decides the cut-off; CSAT (Paper II) has 80 questions and is only qualifying at 33%. Each correct answer in GS-I earns +2, and one-third of the marks (about 0.66) is deducted for every wrong answer, with no penalty for unattempted questions.

What is the eligibility and age limit for UPSC CSE?

You need a Bachelor's degree in any discipline, and final-year students may appear for the Prelims. The age limit is 21 to 32 years for the General category (as on 1 August of the exam year), with relaxations and more attempts for OBC, SC, ST, EWS and PwBD candidates. General candidates get 6 attempts, OBC 9, and SC/ST are unlimited up to the age limit.

How many stages are there in the Civil Services Examination?

There are three stages: the Preliminary examination (objective screening), the Main examination (nine descriptive papers totalling 1750 marks) and a Personality Test / interview of 275 marks. The final merit is based on the Mains and interview together; the Prelims score only decides who qualifies for the Mains.

What is a good score to clear the UPSC Prelims?

It varies every year with paper difficulty, but a net GS Paper I score of roughly 95–100 out of 200 is generally safe for the General category, while the cut-off has occasionally fallen closer to 88. Reserved-category cut-offs are lower. Because of negative marking, your net (not raw) score is what matters.

Which services can I get through the UPSC CSE?

The CSE fills over two dozen services, headed by the IAS, IPS and IFS, and including the IRS, IA&AS, IRMS, IDAS, IPoS and several Group A and Group B central services. The service you are allotted depends on your final rank, your stated preferences, your category and the vacancies available that year.

How should I use mock tests to prepare for the Prelims?

Begin with subject-wise and topic tests to build accuracy across polity, history, geography, economy, environment, science and current affairs, then move to full-length Prelims mocks under the real two-hour clock. Analyse every mock closely — especially your guessing decisions under negative marking — since managing net score is the core skill the Prelims tests.
