How the UPSC Marking Scheme Works

Fact: Both GS Paper I and CSAT (GS Paper II) in Prelims are objective-type with multiple-choice questions and negative marking for incorrect answers.

Fact: Each question carries equal marks within a paper, and a wrong answer generally leads to a deduction of one-third of the marks assigned to that question. Leaving a question unattempted does not attract any penalty.

For aspirants, this means guesswork must be calculated, not random. A disciplined attempt strategy — based on eliminating options logically and skipping wild guesses — is essential to protect your net score.

Fact: Marks obtained in GS Paper I alone are used to decide the Prelims cut-off for different categories; CSAT is only qualifying.

Fact: For CSAT, candidates must secure at least 33% of the total marks, failing which their GS Paper I marks will not be considered, irrespective of how high they are.

In practice, you should aim for a comfortable safety margin in CSAT while maximising your GS Paper I score. Monitoring both gross and net scores in mocks helps you adjust attempts and accuracy.

Fact: Each Mains paper (Essay, GS I–IV, Optional I & II, and language papers) is evaluated manually by examiners who award marks for each question based on content, structure, clarity, and relevance.

Fact: Essay, GS I–IV, and Optional I & II are counted for merit and together add up to 1750 marks. The two language papers are qualifying; failing them can disqualify a candidate from the merit list.

Because there is no negative marking in Mains, you should attempt as many questions as possible with meaningful content, even if you feel less confident about some topics. Leaving questions blank directly reduces your scoring potential.

Fact: The Personality Test (Interview) carries 275 marks, which are added to the 1750 Mains merit marks, giving a total of 2025 marks for final ranking.

Fact: The final merit list and service allocation are based on this combined score, subject to reservation rules and preferences indicated by candidates.

For strategy, this means that while Prelims is the gatekeeper, your ultimate rank depends on sustained performance in Mains and the interview. A few extra marks in each GS paper and a strong interview can significantly change your final service allocation.

Fact: UPSC publishes category-wise cut-offs for Prelims, Mains, and final selection after the exam cycle concludes. These cut-offs vary by year based on exam difficulty and vacancies.

Fact: Reservation policies and relaxation in marks or attempts for certain categories are clearly specified in the Civil Services Examination Rules and official notifications.

Aspirants should study past cut-offs for realistic benchmarking but avoid becoming fixated on exact numbers, since each year's paper difficulty and competition level can change. Targeting a performance margin above previous cut-offs provides a safer buffer.
