The architecture Three stages, one merit list The Civil Services Examination is a single selection broken into three sequential filters. Each is independent in format but cumulative in effect — clear Prelims to write Mains, clear Mains to be called for the Personality Test. Crucially, only Mains and the Personality Test count toward the final rank; Prelims is purely a gate. May–June · Year of exam Prelims — Objective screening test (2 papers, OMR) Two objective papers of 200 marks each, two hours each. Only GS Paper-I marks decide the cut-off; CSAT (Paper-II) is merely qualifying at 33%. Prelims marks are not added to the final rank. August–September · Year of exam Mains — Descriptive examination (9 papers) Two qualifying language papers (A & B) plus seven counted papers — Essay, four GS papers, and two Optional papers. 1,750 counted marks, each counted paper 250 marks over three hours, spread across roughly five days. January–April · Year after exam Personality Test — UPSC interview board 275 marks, conducted at Dholpur House, New Delhi. A board assesses overall personality and suitability for a career in public service. Final rank = Mains (1,750) + Personality Test (275) = 2,025. Stage 1 · Pattern Preliminary Examination pattern Two papers, both objective (MCQ), both two hours, both 200 marks. Paper-I (General Studies) sets the cut-off that decides who writes Mains; Paper-II (CSAT) only needs 33% to qualify. A negative marking of one-third of the marks allotted applies to a wrong answer in both papers. Paper-I · General Studies 100 objective questions of 2 marks each. This is the only Prelims paper that counts toward the qualifying cut-off — your GS Paper-I score alone decides whether you reach Mains. Questions span current events, history, geography, polity, economy, environment, and general science, with most stems now phrased as multi-statement "how many of the above" items rather than single-fact MCQs. See the full GS Paper-I syllabus → Paper-II · CSAT (Civil Services Aptitude Test) 80 objective questions testing comprehension, logical reasoning, decision-making, basic numeracy, and data interpretation at roughly Class-X level. You only need 66/200 (33%) to qualify — CSAT marks do not affect your Prelims rank — but since 2023 the paper has become materially harder, so it can no longer be treated as a free pass. Decision-making questions carry no negative marking. Both papers are compulsory. If you skip CSAT or score below 33%, your GS Paper-I is not evaluated for the cut-off — you are out, regardless of your GS score. The number of candidates cleared for Mains is roughly 12–13 times the vacancies. Stage 2 · Pattern Main Examination pattern Mains is written and descriptive — nine papers in all. Two are qualifying language papers (marks not counted); the other seven — Essay, four General Studies papers, and two Optional papers — carry 250 marks each and add up to the 1,750 counted marks. Every paper runs three hours. Paper-by-paper notes Papers A & B — Qualifying language papers (300 each) One Indian language from the Eighth Schedule plus English. You must score 25% in each. They are purely qualifying — the marks are not added to the merit. If you fail either, the rest of your Mains papers are not evaluated. (Some candidates from specified North-Eastern states and certain PwBD categories are exempt from Paper A.) Paper-I — Essay (250) Two essays in two sections; you pick one topic from each section. Tests structured argument, breadth, and language — same weight as a full GS or Optional paper. Papers II–V — General Studies I to IV (250 each, 1,000 total) GS-I (heritage, history, geography, society), GS-II (polity, governance, social justice, international relations), GS-III (economy, environment, science & tech, security, disaster management), and GS-IV (ethics, integrity, aptitude — includes a case-studies section). Papers VI–VII — Optional subject (250 each, 500 total) Two papers in one optional chosen from the Commission's list of subjects (plus literatures of listed languages). Counts a full 500 marks toward the rank. Medium You may write the Essay, GS, and Optional papers in English or in any Eighth-Schedule language declared at the application stage — but you cannot mix media across papers. Stage 3 · Pattern Personality Test (Interview) Candidates who clear the Mains cut-off are called for the Personality Test — 275 marks, conducted by a UPSC board at Dholpur House, New Delhi. There is no minimum qualifying mark; the score is added directly to the Mains total to form the final merit.

What it assesses Not knowledge for its own sake, but mental and social traits — clarity and logic of thought, balance of judgement, depth of interest, leadership, and integrity — i.e., suitability for a career in public service. The question paper is your DAF The board questions you from your Detailed Application Form — home state, education, work, hobbies, and service/cadre preferences — alongside current affairs and situational questions. Weight At 275 of 2,025 marks (≈13.6%), the interview routinely swings ranks by 50–100 marks and can change service allocation. Negative marking & qualifying rules Prelims negative marking One-third of the marks assigned to a question is deducted for each wrong answer in both GS Paper-I and CSAT. No penalty for questions left blank. CSAT's decision-making questions carry no negative marking. CSAT is qualifying (33%) Paper-II only needs 66/200. Below that, you are disqualified even with a high GS score. Mains language papers are qualifying (25%) Papers A and B (Indian language + English) need 25% each. The marks don't count, but failing either means the counted papers aren't evaluated. Mains is descriptive No negative marking; answers are written within word limits (typically 150/250 words) under time pressure — about 20 questions across three hours per GS paper. Only Mains + Interview count Prelims is a screening gate; its marks are discarded once you qualify for Mains. Where the marks are Marks distribution & final merit The final rank is the sum of Mains (1,750 counted marks) and the Personality Test (275) — Prelims contributes nothing. Within the counted total, General Studies dominates with 1,000 marks; the Optional contributes 500; the Essay 250. Final-rank composition (out of 2,025) General Studies (4 papers) Optional (2 papers) Personality Test Attempts, age & eligibility The pattern is the same for everyone, but the number of attempts and the upper age limit vary by category (as on 1 August of the exam year). A graduate degree from a recognised university is the basic qualification. Minimum age is 21. Final-year degree students may appear in Prelims but must produce proof of passing for Mains. Figures follow the standing notification; always confirm against the year's official notification. Frequently asked Questions aspirants ask about the pattern No. Prelims is only a screening test — its marks decide who qualifies for Mains and are then discarded. The final rank is built from Mains (1,750 counted marks) + the Personality Test (275) = 2,025. One-third of the marks allotted to a question is deducted for each wrong answer in both GS Paper-I and CSAT. There is no penalty for unattempted questions, and CSAT's decision-making questions carry no negative marking. Nine. Two qualifying language papers (Paper A — an Indian language, and Paper B — English, 300 marks each at 25% qualifying), plus seven counted papers — Essay, General Studies I–IV, and two Optional papers — at 250 marks each, totalling 1,750 counted marks. Qualifying. You need 33% (66/200) in CSAT (Paper-II). It does not affect your Prelims rank, but it is compulsory — fail it and your GS Paper-I won't be evaluated for the cut-off. Since 2023 it has become noticeably harder, so prepare for it. 2,025 — Mains written total (1,750) plus the Personality Test (275). General Studies (1,000) and the Optional (500) together make up three-quarters of it.
