Critical Rules of the Marking Scheme for UPSC Prelims

The upsc prelims marking scheme follows strict protocols regarding how answers are recorded and penalized. 

Negative Marking Protocol

The penalty system is designed to discourage blind guessing. For every question where a wrong answer is given by the candidate, one-third (1/3) of the marks assigned to that question will be deducted as a penalty.

Multiple Circle Penalties

The way the UPSC preliminary marking scheme handles multiple responses is one of its distinctive features. Even if one of the candidate's responses is accurate, if they give more than one response for a single question, it will be considered incorrect. In this case, the usual penalty of one-third will still be applicable.

Unanswered Questions

If a question is left blank (no answer is given by the candidate), there will be no penalty or negative marking for that question. This makes "intelligent skipping" a vital skill for the 2026 attempt.

Calculating Your Score

To estimate your performance based on the upsc cse prelims marking scheme, use the following steps:

  1. Multiply the number of correct answers by 2 (for GS I) or 2.5 (for CSAT).

  2. Multiply the number of incorrect answers by 0.66 (for GS I) or 0.83 (for CSAT).

  3. Subtract the total negative marks from the total positive marks to get your final score.
