TEST & SCORE: Your Blueprint for Success̥®.

The UPSC Civil Services Examination (CSE) is a nationwide competitive exam conducted annually by the Union Public Service Commission to recruit candidates for top administrative positions in the Government of India. It serves as the gateway to 24 highly prestigious services, including the Indian Administrative Service (IAS), Indian Police Service (IPS), and Indian Foreign Service (IFS). [1, 2, 3]

Three-Stage Selection Process

The entire examination cycle spans roughly one year and filters candidates through three distinct phases: [4, 5, 6, 7]

1. Preliminary Examination (Prelims)

  • Nature: Objective-type screening test with multiple-choice questions (MCQs). [8, 9]
  • Papers: Consists of two compulsory papers of 200 marks each, lasting 2 hours each.
    • General Studies (GS) Paper I: Covers History, Geography, Polity, Economy, Environment, and Current Affairs. Scores in this paper determine the cut-off merit list.
    • Civil Services Aptitude Test (CSAT) / Paper II: Evaluates reasoning, comprehension, and analytical skills. It is qualifying; you only need a minimum score of 33% (66 marks). [8, 9, 10, 11, 12, 13]
  • Negative Marking: One-third (1/3) of the marks assigned to a question are deducted for every incorrect response. [11, 13]
  • Note: Marks scored in Prelims are purely for qualification and are not counted in the final merit list. [8, 11]

2. Main Examination (Mains)

  • Nature: Descriptive, offline written test consisting of 9 papers over several days. [10, 13, 14]
  • Qualifying Papers: Paper A (Compulsory Indian Language) and Paper B (English). Both carry 300 marks, require a minimum score of 25%, and do not count toward final merit. [12, 14, 15, 16, 17]
  • Merit-Ranked Papers: Marks from the remaining 7 papers (250 marks each, totalling 1750 marks) dictate final rankings.
    • Paper I: Essay.
    • Paper II–V: General Studies (GS I, GS II, GS III, GS IV covering Ethics).
    • Paper VI–VII: Two papers focused on a singular Optional Subject chosen by the candidate. [8, 12, 13, 14, 18]

3. Personality Test (Interview) [19]

  • Nature: Face-to-face evaluation by a board of UPSC experts to assess mental alertness, leadership potential, integrity, and critical thinking. [9, 13]
  • Weight: Carries 275 marks. [13]
  • Final Score: Total marks from the Mains written papers (1750) + Interview (275) form a grand total of 2025 marks, which decides final ranking and service allocation. [13, 20]

Core Eligibility Criteria

  • Educational Qualification: A candidate must hold a bachelor’s degree in any discipline from a recognized university. Final-year students are eligible to apply on a provisional basis. [21, 22]
  • Nationality: Must be an Indian citizen for the IAS, IFS, and IPS. Other services permit specified PIOs and subjects of neighboring countries. [21, 23, 24, 25]
  • Age Limits & Attempt Restraints: Calculated as of August 1st of the exam year: [9]
