UPSC Civil Services 2026: Mains 21 Aug, Pattern, Posts

UPSC Civil Services 2026: Mains starts 21 August

UPSC Civil Services Examination 2026 is recruiting for 933 posts across the Group A and Group B services, and the Main examination begins on 21 August 2026. If you cleared the Preliminary examination, that is 17 days away at the time of writing.

The cycle so far: UPSC notified the examination on 4 February 2026, applications ran to 27 February, the Preliminary examination was held on 24 May 2026, and the Prelims result was declared on 15 June 2026. The Detailed Application Form I window ran from 19 to 28 June 2026. What remains is the Mains, then the Personality Test.

One thing worth fixing at the outset, because candidates lose marks to it every year. Two of the nine Mains papers do not count towards your rank at all, and two more decide almost everything. Getting that allocation wrong in the final fortnight is expensive, so the paper structure section below is the part of this page to read first.

The Mains schedule, day by day

The Main examination runs across five days, with two sessions on each day.

Session timings are 9:00 am to 12:00 noon for the forenoon paper and 2:30 pm to 5:30 pm for the afternoon paper. Each paper is three hours.

Note the gap. The examination breaks after 23 August and resumes on 29 August, giving five clear days in between. That window usually falls before the optional subject papers, and how you use it matters: candidates who treat it as recovery time and candidates who treat it as revision time end up with noticeably different optional scores.

Mains paper structure, and what actually counts

This is the table to internalise.

Seven papers at 250 marks each gives 1,750 marks that count. The Personality Test adds 275. Final merit is therefore out of 2,025 marks.

Papers A and B carry 600 marks between them and contribute nothing to your rank. They are pass or fail. The qualifying standard is modest, typically set around 25 per cent, but the consequence of failing is absolute: if you do not clear Paper A or Paper B, UPSC does not evaluate your other seven papers at all. A candidate can write an excellent Essay, four strong General Studies papers and two good optional papers, and have none of them read.

Candidates from English-medium backgrounds underestimate Paper A, the Indian language paper. Candidates educated in regional-medium schools sometimes underestimate Paper B. Both mistakes end the attempt in exactly the same way, and both are avoidable with a few hours of practice on the prescribed formats: comprehension, précis, translation, and short composition.

Where the marks are actually decided

Of the 1,750 counted marks, the optional subject carries 500 across two papers. That is more than any single General Studies paper and more than the Essay. It is also the most controllable component, because it is a defined syllabus you have studied for months rather than an open-ended current affairs canvas.

The four General Studies papers carry 1,000 marks combined. General Studies IV, the ethics paper, is the one candidates most often underprepare and the one where marks move most for modest effort, because a structured approach to case studies produces visible gains.

The Essay at 250 marks is a single paper with two essays of 125 marks each. It rewards structure and breadth of illustration rather than specialised knowledge, and it is frequently the difference between a rank and a near miss.

Prelims pattern, for the next cycle

If you are targeting CSE 2027, the Preliminary examination is where the funnel narrows hardest.

Both papers are objective with negative marking, and both are two hours. Paper II being qualifying at 33 per cent means you need 66.7 marks out of 200 to pass it, and marks above that add nothing. Paper I alone decides the Prelims cutoff.

Prelims marks do not carry into the Mains or the final merit. They exist only to shortlist. That is worth remembering, because candidates sometimes treat a high Prelims score as a head start, and it is not one.

Vacancies

CSE 2026 carries 933 vacancies, including 33 reserved for Persons with Benchmark Disabilities. These are distributed across the services, and the service-wise split is finalised later in the cycle rather than announced with the notification.

The services filled through this examination include the Indian Administrative Service, the Indian Police Service, the Indian Foreign Service, the Indian Revenue Service in both Income Tax and Customs and Indirect Taxes, the Indian Audit and Accounts Service, the Indian Railway Management Service, the Indian Defence Accounts Service, the Indian Information Service, and several other Group A and Group B services including the DANICS and DANIPS cadres.

Service allocation depends on your final rank and the preferences you submit in the Detailed Application Form, along with category and cadre rules. The top ranks generally clear IAS and IFS; the range of services accessible widens considerably as you move down the list.

Eligibility

On age, candidates must be between 21 and 32 years as on 1 August 2026, with relaxation of 3 years for OBC candidates, 5 years for SC and ST candidates, and further relaxation for defence service personnel, ex-servicemen and PwBD candidates as specified.

On attempts, general category candidates get 6 attempts, OBC candidates get 9, and SC and ST candidates have no numerical limit but remain bound by the upper age limit. PwBD candidates get 9 attempts in the general and OBC categories. An attempt counts when you appear in at least one paper of the Preliminary examination.

On education, a bachelor's degree from a recognised university is required. Final-year students may apply for the Preliminary examination but must produce proof of passing before the Mains.

The application fee is Rs 100 for general, OBC and EWS male candidates. Female candidates and SC, ST and PwBD candidates pay nothing.

Salary and what the job pays

An officer entering through this examination begins at Level 10 of the pay matrix with a basic pay of Rs 56,100 a month, plus dearness allowance, house rent allowance by city class, and transport allowance. Gross monthly pay at entry commonly works out well above the basic figure.

Progression runs through defined stages: Junior Time Scale at Level 10, Senior Time Scale at Level 11, Junior Administrative Grade at Level 12, Selection Grade at Level 13, Super Time Scale at Level 14, and upward to Level 15, 16, 17 and finally Level 18 for a Cabinet Secretary at Rs 2,50,000.

The non-cash side is substantial and frequently understated in comparisons: official accommodation, official vehicle and staff at appropriate levels, medical facilities, security of tenure, and pension benefits under the applicable rules. The counterweight is genuine and worth stating too: postings are transferable, early district assignments can be remote, and the working hours in field postings are long.

Preparing in the final fortnight

With the Mains 17 days out, the useful moves are narrow and specific.

Stop consuming new material. Two weeks before a descriptive examination, the marginal value of a new source is near zero and the cost in revision time is real. Work from notes you already have.

Write full-length papers under the clock. Three hours, 20 questions, by hand. Mains is as much an endurance and time-allocation problem as a knowledge one, and candidates who have not written a full paper in weeks discover on day one that their hand tires and their last five answers suffer.

Confirm your language papers are safe. If Paper A or Paper B is a genuine risk for you, a few hours on the prescribed formats is the highest-return time available anywhere in this fortnight, because it protects all 1,750 of your other marks.

Revise the optional. It carries 500 marks, it is the most controllable component, and the five-day gap from 24 to 28 August exists precisely for this.

Prepare answer structure rather than content for General Studies IV. Ethics case studies reward a consistent framework applied calmly far more than they reward remembering thinkers. Settle on a template you can apply to any dilemma: identify the stakeholders, name the competing values, set out the options with their consequences, then commit to a decision and justify it. Applying one reliable structure under time pressure beats recalling a dozen philosophers you cannot deploy.

What the four General Studies papers cover

Knowing the boundaries between them matters, because Mains questions are set to a paper's remit and answers that drift into another paper's territory lose marks.

General Studies I covers Indian heritage and culture, modern Indian history and the freedom struggle, post-independence consolidation, world history, Indian society, and physical geography including resource distribution and geophysical phenomena.

General Studies II covers the Constitution, polity, governance, social justice and international relations: the structure and functioning of the executive, legislature and judiciary, devolution of powers, statutory and constitutional bodies, government policies and interventions, welfare schemes, and India's relations with its neighbourhood and the wider world.

General Studies III covers the economy, agriculture, science and technology, environment, internal security and disaster management: growth and development, budgeting, cropping patterns, food processing, land reforms, infrastructure, technology missions, biodiversity, and security challenges including cyber security and money laundering.

General Studies IV covers ethics, integrity and aptitude, tested largely through case studies. It examines attitude, emotional intelligence, public service values, probity in governance, and the application of ethical reasoning to administrative dilemmas.

Current affairs cut across all four rather than sitting in any one of them, which is why a standalone current affairs approach works less well than mapping developments onto the relevant paper as you read them. A single news development on, say, a river-linking project can supply material for geography in Paper I, federal disputes in Paper II, and environmental impact in Paper III, and the candidate who files it three ways has three usable answers rather than one.

Exam day practicalities

Carry your e-admit card and the photo identity document specified on it. UPSC is strict on both and admits nobody without them.

Reach the centre well before the reporting time. Gates close ahead of the session start and UPSC does not admit latecomers, in either the forenoon or the afternoon session.

Take only permitted items. Mobile phones, smart watches, electronic devices and any communication equipment are barred, and centres do not reliably offer storage. Carry black ballpoint pens, since answer scripts must be written in black ink.

Plan the lunch gap on the three double-paper days. The break between a 12:00 noon finish and a 2:30 pm start is short once you account for exit and re-entry queues, and candidates who skip food entirely tend to fade in the afternoon paper.

After the Mains

Results follow some weeks after the last paper. Candidates who clear the Mains submit the Detailed Application Form II and are called for the Personality Test, worth 275 marks, held at UPSC's office in New Delhi.

The Personality Test is not a knowledge examination. The board assesses clarity of thought, balance of judgement, depth of interest, and suitability for a career in public service, drawing heavily on your DAF: your home state, your graduation subject, your hobbies, your service preferences and your work experience. Everything you entered there is fair material for questioning, which is why the DAF deserves care when you fill it.

Final merit combines the Mains 1,750 and the Personality Test 275 for a total of 2,025 marks. Service allocation follows from that rank and your stated preferences.

Candidates who do not clear this stage should note that the preparation transfers directly. The UPSC CDS route into the armed forces, the UPSC CAPF Assistant Commandant route into the paramilitary, and state public service commission examinations all draw on substantially the same base.

Frequently asked questions

When is the UPSC Mains 2026 exam? The UPSC Civil Services Main examination 2026 is held on 21, 22, 23, 29 and 30 August 2026, across five days with two sessions each day. The forenoon session runs from 9:00 am to 12:00 noon and the afternoon session from 2:30 pm to 5:30 pm, with every paper lasting three hours. Note the five-day gap between 23 and 29 August.

How many vacancies are in UPSC CSE 2026? There are 933 vacancies, including 33 reserved for Persons with Benchmark Disabilities. They cover the Indian Administrative Service, Indian Police Service, Indian Foreign Service, Indian Revenue Service and other Group A and Group B services. The service-wise split is finalised later in the cycle rather than announced with the February notification.

Which UPSC Mains papers count towards the final merit? Seven of the nine papers count: the Essay, the four General Studies papers, and the two optional subject papers, at 250 marks each for a total of 1,750. Paper A, the Indian language paper, and Paper B, English, carry 300 marks each but are qualifying only and contribute nothing to your rank. The Personality Test adds 275, making the final merit out of 2,025 marks.

What happens if I fail the UPSC language papers? Your other seven papers are not evaluated at all. Papers A and B are qualifying, typically at around 25 per cent, and failing either means UPSC does not assess your Essay, General Studies or optional papers, however well you wrote them. This is why a few hours of format practice on comprehension, précis and translation is the highest-return preparation available to anyone at risk.

What is the UPSC CSE 2026 exam schedule so far? UPSC notified the examination on 4 February 2026 with applications open to 27 February and a correction window from 28 February to 3 March. The Preliminary examination was held on 24 May 2026 and its result was declared on 15 June 2026. The Detailed Application Form I window ran from 19 to 28 June 2026, and the Main examination runs from 21 to 30 August 2026.

What is the age limit and attempt limit for UPSC CSE? Candidates must be 21 to 32 years as on 1 August 2026, with 3 years relaxation for OBC and 5 years for SC and ST candidates, plus further relaxation for defence personnel, ex-servicemen and PwBD candidates. General category candidates get 6 attempts, OBC candidates 9, and SC and ST candidates have no numerical cap but remain bound by the age limit. An attempt counts once you appear in any Preliminary paper.

Do UPSC Prelims marks count in the final merit? No. The Preliminary examination is only a screening stage and its marks do not carry into the Mains or the final ranking. Paper II, the CSAT, is itself qualifying at 33 per cent, meaning 66.7 marks out of 200, with anything above that adding nothing. Only Paper I decides who reaches the Mains.

What is the salary of an IAS officer? Entry is at Level 10 of the pay matrix with a basic pay of Rs 56,100 a month, plus dearness allowance, house rent allowance by city class and transport allowance. Progression runs through Level 11, 12, 13, 14, 15, 16 and 17, up to Level 18 at Rs 2,50,000 for a Cabinet Secretary. Official accommodation, transport, medical facilities and pension benefits add substantially to the package.

How much weight does the optional subject carry in UPSC Mains? The optional subject carries 500 marks across two papers of 250 each, which is more than any single General Studies paper and more than the Essay. It is also the most controllable component of the Mains, since it follows a defined syllabus rather than an open-ended current affairs range, which makes it the highest-priority revision target in the final weeks.

What should I carry to the UPSC Mains exam? Your e-admit card and the photo identity document specified on it, plus black ballpoint pens, since answer scripts must be written in black ink. Mobile phones, smart watches, electronic devices and communication equipment are prohibited, and centres do not reliably provide storage. Arrive well before the reporting time, as gates close ahead of the session start and latecomers are not admitted.

What happens after the UPSC Mains examination? Results are declared some weeks after the final paper. Candidates who qualify submit the Detailed Application Form II and are called for the Personality Test at UPSC's office in New Delhi, worth 275 marks. The board draws heavily on your DAF, covering your home state, graduation subject, hobbies, work experience and service preferences, so those entries should be filled with care.

Which services are filled through UPSC CSE? The Indian Administrative Service, Indian Police Service, Indian Foreign Service, Indian Revenue Service in both Income Tax and Customs and Indirect Taxes, Indian Audit and Accounts Service, Indian Railway Management Service, Indian Defence Accounts Service, Indian Information Service, and various other Group A and Group B services including DANICS and DANIPS. Allocation depends on your final rank, your stated preferences, and category and cadre rules.
