Why the Mains is decisive
Prelims only qualifies you; the Mains (1750 marks) plus Interview (275 marks) decide the final rank. Within Mains, the difference between rankers is rarely knowledge — it is answer quality: structure, relevance, balance and presentation under a brutal time constraint.
The nine papers
| Paper | Marks | Counts? |
|---|---|---|
| Paper A — Indian Language | 300 | Qualifying |
| Paper B — English | 300 | Qualifying |
| Essay | 250 | Merit |

Merit total = 1750; the two language papers are only qualifying.
Answer-writing strategy
- Decode the directive — “discuss, examine, critically analyse, comment” each demand a different treatment;
- Structure every answer — crisp introduction, a body in points/sub-headings, a constructive conclusion;
- Be multi-dimensional — social, economic, political, ethical, environmental, international angles;
- Substantiate — data, committees, schemes, judgments, examples;
- Manage time — ~7-8 minutes per 10-marker; attempt all questions;
- Practise daily and get feedback.
UPSC angle
Knowledge gets you to the exam hall; structure and presentation get you the rank. Decode the directive, write in a clear intro-body-conclusion arc, and substantiate every claim.
