ToggleThe UPSC Civil Services Exam selects officers for the IAS, IPS, IFS (Foreign Service) and other Group ‘A’/‘B’ services through three sequential stages: Preliminary Examination, Main Examination, and Personality Test (Interview). Think of them as a funnel—each stage tests you differently and more deeply. Crack the three stages of UPSC exam with clarity.
How the Three Stages Compare
| Stage | What it tests | Papers | Marks counted for rank | Result basis |
|---|---|---|---|---|
| Prelims | Breadth of knowledge, speed, elimination, risk control | GS-I, CSAT (GS-II) | No (qualifying + screening) | Cut-off based on GS-I; CSAT is qualifying (33%) |
| Mains | Depth, structure, analysis, expression, ethics | 9 papers (2 qualifying + 7 merit) | Yes (1750) | Aggregate of 7 merit papers |
| Interview | Personality, judgment, balance, awareness | 1 board interview | Yes (275) | Final rank = Mains (1750) + Interview (275) |
Purpose:
Screening—tests range and speed under uncertainty.
Papers (same day):
- GS Paper I (200 marks, 2 hours): Polity, Economy, History, Geography, Environment/Ecology, Science & Tech, International/Current Affairs, Government schemes, etc.
- CSAT (GS Paper II) (200 marks, 2 hours): Comprehension, logical reasoning, analytical ability, basic numeracy, data interpretation, decision-making.
Key Rules:
- Negative marking: ⅓rd of the marks for a wrong answer.
- CSAT is qualifying: You must score 33% (66/200); its score doesn’t add to merit.
- Cut-off applies only to GS Paper I.
Strategy Pointers:
- Treat GS-I as the merit gate; calibrate attempts and accuracy.
- Do not ignore CSAT—maintain steady practice (RC + reasoning + numeracy).
- Build a notes → revision → test cycle; analyze error types (conceptual vs careless vs guess).

Tests depth, clarity, analysis, and written expression across subjects.
