Introduction to UPSC Preliminary Examination

The UPSC Preliminary Examination is the first stage of the Civil Services Examination (CSE) conducted by the Union Public Service Commission (UPSC). It serves as a screening test to shortlist candidates for the next stage — the Main Examination. The Prelims test a candidate’s general awareness, analytical ability, and aptitude through objective-type questions.

Structure of the Prelims Examination

The Prelims consists of two compulsory papers conducted on the same day:

  1. Paper I – General Studies (GS)

    • Total Marks: 200

    • Duration: 2 hours

    • Type: Objective (Multiple Choice Questions)

    • Purpose: To test knowledge of current events, Indian history, polity, geography, economy, environment, and general science.

    • Qualifying Nature: Marks are counted for merit to qualify for Mains.

  2. Paper II – CSAT (Civil Services Aptitude Test)

    • Total Marks: 200

    • Duration: 2 hours

    • Type: Objective (MCQs)

    • Purpose: To evaluate comprehension, logical reasoning, decision-making, and basic numeracy skills.

Key Features of the UPSC Prelims

  • Conducted once a year, usually in May or June.

  • Negative marking: 1/3rd marks are deducted for every incorrect answer.

  • Both papers are conducted on the same day in two sessions.

  • Objective in nature, but demands deep conceptual clarity and wide coverage.

  • The marks of Prelims are not counted in the final merit list — it’s only a qualifying stage for the Mains Examination.
