UPSC Civil Services (IAS/IPS/IFS) — Complete Exam and Career Guide
A detailed guide to UPSC Civil Services — Prelims, Mains, Interview stages, eligibility, number of attempts by category, list of services, salary, and career progression for IAS, IPS, IFS, and IRS officers.
No other exam in India carries quite the same weight as the UPSC Civil Services Examination. Over a million candidates register every year. A few hundred make it. The people who clear it don't just get a job — they get a career that shapes policy, administers districts, handles foreign affairs, and leads enforcement agencies.
This guide breaks down exactly what the exam looks like, who can appear, how many times, and what happens after selection.
What is the Civil Services Examination?
The Union Public Service Commission conducts this exam to recruit officers for the All India Services (IAS, IPS, IFoS) and the Central Services (Group A and Group B). It's a single exam — one application, one Prelims, one Mains — that feeds into all these services depending on your rank and preference.
The exam is spread across roughly a year, from the April Prelims to the final recommendation in May-June the following year.

- History of India and Freedom Struggle
- Geography (Physical, Social, Economic)

Stage 2 — Main Examination (Mains)
Held in September. Written papers, mostly subjective:
| Paper | Marks | Nature |
|---|---|---|
| Essay (Paper A) | 250 | Counted in merit |
| GS Paper I | 250 | India Heritage, Culture, Geography, History |
| GS Paper II | 250 | Governance, Polity, IR, Constitution |
| GS Paper III | 250 | Technology, Economy, Environment, Security |
| GS Paper IV | 250 | Ethics, Integrity, Aptitude |
| Optional Paper I | 250 | Chosen subject |
| Optional Paper II | 250 | Chosen subject |
| Indian Language (Paper A) | 300 | Qualifying |
| English (Paper B) | 300 | Qualifying |
Language papers (Paper A and B) are qualifying — you need 25% to pass. They don't count toward merit.
Popular optional subjects include Anthropology, Geography, History, Public Administration, Sociology, Political Science, and PSIR. The "best" optional varies by background and is honestly a personal decision — pick what you can study for 400+ hours without losing interest.
Stage 3 — Personality Test (Interview)
275 marks. Conducted at UPSC Bhavan, New Delhi. The board tests your personality, judgment, leadership potential, and awareness of current affairs. This is not a GK quiz. They probe your opinions, how you handle disagreement, and whether you can hold a reasoned position under pressure.
Final merit = Mains marks + Interview marks (out of 2025 total).

Preparation Reality Check
Time required: Most successful candidates take 1.5–3 years of dedicated preparation. What actually makes the difference:- A stable optional (studied deeply, not superficially)
- Answer writing practice for Mains — this is where most candidates underperform
- Consistent editorial reading (The Hindu, Indian Express) for GS Paper II and Essay
- Mock interview participation in the final stage
