The UPSC Civil Services Examination (CSE) recruits officers for the IAS, IPS, IFS and other Group A and Group B central services. It is held in three stages: Preliminary, Main and Personality Test.
Stage 1: Preliminary examination

| GS Paper II (CSAT) | 80 | 200 | 2 hours | Qualifying: minimum 33% |
- Both papers are objective (multiple choice) and held on the same day.
- Negative marking: one-third of the marks assigned to a question is deducted for each wrong answer (0.66 in GS I; 0.83 in CSAT).
- Prelims marks are not counted in the final merit; they are used only to shortlist candidates for Mains (about 12–13 times the number of vacancies).
Stage 2: Main examination

How the stages connect
- Prelims filters candidates; its score is discarded after shortlisting.
- Mains decides most of the final rank, so answer-writing practice matters more than any other single skill.
- The interview can change the final rank significantly; marks usually vary widely across candidates.
