Many aspirants get confused after the exam:
"How do I calculate UPSC prelims marks?"
"How does negative marking work?"
This calculator is designed to clear all your doubts!
Before you use the UPSC calculator, understand the pattern of the Prelims:
Paper | Subject | Total Marks | No. of Questions | Duration | Negative Marking |
---|---|---|---|---|---|
Paper I | General Studies (GS) | 200 | 100 | 2 hours | Yes (1/3rd per wrong answer) |
Paper II | CSAT (Aptitude Test) | 200 | 80 | 2 hours | Yes (1/3rd per wrong answer) |
Note: CSAT is qualifying only. You must score 33% (66 marks) to pass.
Paper | Correct Answers | Incorrect Answers | Formula | Total Score |
---|---|---|---|---|
Paper I (GS) | Each correct answer = 2 marks | 1/3rd of 2 marks deducted per wrong answer | (Correct × 2) - (Incorrect × 0.66) | Out of 200 |
Paper II (CSAT) | Each correct answer = 2.5 marks | 1/3rd of 2.5 marks deducted per wrong answer | (Correct × 2.5) - (Incorrect × 0.83) | Out of 200 |
Let’s say you attempted 80 questions:
Correct: 65
Wrong: 15
Then your score will be:
(65 × 2) - (15 × 0.66) = 130 - 9.9 = 120.1
Instead of doing this manually, just enter your numbers in our UPSC prelims marks calculator and get your score instantly!
UPSC Negative Marking Calculation Explained
Negative marking is a key part of UPSC prelims. It is designed to discourage guessing. Here's how it works:
• For every wrong answer in Paper I, 1/3rd of the mark is deducted.
• So for a 2-mark question, 0.66 marks will be deducted for every wrong answer.
• Unattempted questions carry no penalty.
