How to Calculate CSAT Marks Steps Guide

Step 1: Understand the Marking Scheme

  • Marks per Question: Each question in CSAT carries 2.5 marks.
  • Negative Marking: Approximately, for every incorrect answer, 1/3rd of the marks assigned to that question are deducted, which is roughly -0.833 marks per incorrect answer.
  • Unanswered Questions: No marks are awarded or deducted for unanswered questions.

Step 2: Count Correct and Incorrect Answers

  • Start by identifying the number of questions you answered correctly and incorrectly based on the official answer key provided by UPSC.

Step 3: Calculate the Raw Score

  • Correct Answers: Multiply the number of correct answers by 2.5 to calculate the total marks obtained from correct responses.
  • Incorrect Answers: Multiply the number of incorrect answers by -0.833 to determine the penalty for incorrect responses.

Step 4: Determine the Net Score

  • Subtract the penalty (marks deducted for incorrect answers) from the total marks obtained for correct answers to get the net score.

Step 5: CSAT Marks Calculator

Let’s illustrate with an example:

Assume a candidate attempted 65 questions in the CSAT exam:

  • Out of these, 50 answers were correct, and 15 were incorrect.


  • Number of Correct Answers: 50
    • Raw Score for Correct Answers: 50 × 2.5 = 125 marks
  • Number of Incorrect Answers: 15
    • Penalty for Incorrect Answers: 15 × 0.833 = 12.45 marks (rounded to 12.5 marks)

Net Score Calculation:

  • Net Score = Raw Score – Penalty
  • Net Score = 125 – 12.5 = 112.5 marks

Tips for Accurate Calculation

  • Use Official Answer Key: Always refer to the official answer key provided by UPSC to ensure accuracy in counting correct and incorrect answers.
  • Double-check Calculations: Verify your calculations to avoid errors in subtracting penalties or multiplying marks.
  • Practice with Mock Tests: Familiarize yourself with the marking scheme through mock tests and previous years’ question papers to improve accuracy in calculating scores.
