How to calculate marks in UPSC prelims?

**How to calculate negative marking in UPSC exam?**

Let us consider the below example:

UPSC Prelims consist of two papers General Studies Paper-I and CSAT Paper – II. General Studies Paper-I has 100 questions for 200 marks (2 marks per question) and duration for two hours.

Suppose among 100 questions if you have answered 75 correct and 25 incorrect **.**

**Calculation of marks for Paper I:**

Correct answers 75 x 2 = 150 marks.

Each incorrect answer carries a negative marking of o.33%, which means for every wrong answer 0.66 marks will be deducted.

Therefore, in the above example if 25 questions were answered incorrectly then the negative marking for 25 incorrect answers would be 25 x 0.66 = **16.5.**

As a result, 16.5 marks would be deducted from the correctly answered questions.

i.e., Final Score for Paper-I: 150 – 16.5 = **133.5**

Now, let’s apply the same for paper II. ** **

**Calculation of marks for Paper II:**

UPSC Prelims Paper II CSAT has 80 questions for 200 marks and each question carrying 2.5 marks.

There is no negative marking from Question number 74 to 80 as the questions are based on decision making and UPSC does not deduct marks for these questions.

Suppose among 80 questions if a candidate has answered 65 correct and 15 incorrect and thinking that the candidate has got 15 incorrect answers from Question numbers 1 to 73 and 5 incorrect answered from question number 74 to 80 (the decision making questions).

Then, the total score of the candidate in CSAT Paper II would be:

Correct answers 50 x 2.5 = 137.5 marks

Incorrect answers from **Q: 1-73**= 15 x 0.83 = 12.45

Total Score in UPSC Prelims Paper II would be: 137.5 – 12.45 = **125.05**

Therefore, the total score that a candidate would have scored in the UPSC Prelims Exam would be: **Total Score (Paper 1 + Paper 2): **133.5+ 125.05 **= 258.55**
