Prelims Paper I & Prelims Paper II

Prelims ExamNo of QuestionsTotal MarksMaks for each right answerMarks for each wrong answer
Preliminary Paper I10020020.66
Preliminary Paper II802002.50.83

Calculation method for UPSC Prelims Paper I:

IAS Prelims Paper I had 100 questions and each question carrying 2 marks. The total paper is of 200 marks.

If you have answered 60 questions correctly and 40 questions incorrectly then you score calculation would be:

Right Answers = 60 * 2 marks ( For each right answer)

Total Marks for right answers = 120

Now we will subtract the 0.33 % for each negative answer.

Wrong answers = 40 * 0.66 (For each wrong answer)

Total marks lost in negative marking = 40*0.66 = 26.4

So the total score after negative marking = Total marks for correct answers – Total marks for incorrect answers.

In this case, the final score of IAS Prelims paper I = 120-26.4 = 95.6

Calculation Method for UPSC Prelims Paper II:

Calculate Your UPSC Exam Score – IAS Prelims Paper II marks are also calculated in the same method. However, there are only 80 questions in Paper II so each right answer gives you 2.5 marks and each wrong answer leads to the deduction of 0.83 marks as per 1/3rd rule. There are a total of 80 questions for 200 marks and each question is worth 2.5 marks.

UPSC Prelims Paper II Score Calculation example:

Let’s Calculate the UPSC Exam Score, where the candidate has given 60 right answers and 20 wrong answers. Let’s calculate the score

Right Answers = 60 * 2.5 (For each right answer)

Total Marks before negative marking = 150

Wrong Answers = 20 * 0.83 (For each wrong answer)

Total Marks lost in negative marking = 16.6

The effective final score for the candidate in Prelims Paper II = 150-16.6 = 133.4

So if we calculate the final score for this candidate in Prelims after negative marking then the total score he would get is:

Prelims Paper I score after negative marking = 95.6

Prelims Paper II score after negative marking = 133.4

The final score would be after negative marking = 95.6+133.4 = 229

Once you go through this article thoroughly, you will be able to calculate marks on your own.
