How to Calculate UPSC Prelims Marks
Calculating your UPSC Prelims score is simple. You only need to calculate the score for General Studies (GS) Paper-I, as Paper-II (CSAT) is only for qualifying.
Here is the main formula to find your GS Paper-I score:
Total Score = (Number of Correct Answers × 2) – (Number of Wrong Answers × 0.66)
Let’s break it down:
- Count your correct answers. Multiply that number by 2 (since each question is worth 2 marks).
- Count your wrong answers. Multiply that number by 0.66 (the penalty for a wrong answer).
- Subtract the penalty (step 2) from your positive score (step 1).
- Questions you did not attempt are not counted. They give you zero marks.
Example:
- You attempted 80 questions in GS Paper-I.
- Correct Answers: 60
- Wrong Answers: 20
- Unattempted Questions: 20
Your score would be:
- Marks for correct answers: XXX
- Marks deducted for wrong answers: XXX
- Your Final Score: XXX
How to Calculate Negative Marking in UPSC
UPSC uses a penalty system for wrong answers to stop candidates from guessing too much. This is called negative marking.
- For every wrong answer in the Prelims exam, one-third (1/3) of the marks for that question will be taken away from your total score.
This rule applies to both GS Paper-I and CSAT Paper-II.
How UPSC Prelims Marks are Calculated
The final marks for the UPSC Prelims are calculated only from GS Paper-I. The CSAT (Paper-II) score is not added to this total. You just need to pass CSAT.
Here’s the step-by-step process:
- Check Your Answers: Compare your answers with an official or reliable answer key.
- Count Correct & Wrong: Separately count how many questions you got right and how many you got wrong in GS Paper-I. Ignore the questions you didn’t answer.
- Use the Formula: Apply the formula: Total Score = (Correct Answers × 2) – (Wrong Answers × 0.66).
- Check CSAT Score: Make sure you have scored at least 66 marks (33%) in CSAT. If you don’t, your GS Paper-I will not be checked, and you will not qualify.
How to Calculate Negative Marks in UPSC Prelims
To find out exactly how many marks you’ll lose from wrong answers, use this simple calculation.
- For GS Paper-I: Each question is worth 2 marks. The penalty is 1/3 of 2, which is approximately 0.66 marks.
- Total Penalty = Number of Wrong Answers × 0.66
- For CSAT Paper-II: Each question is worth 2.5 marks. The penalty is 1/3 of 2.5, which is approximately 0.83 marks.
- Total Penalty = Number of Wrong Answers × 0.83
How to Calculate Marks in UPSC Prelims
Here is a summary of the calculation process:
- Focus on GS Paper-I: Your selection for the Mains exam depends only on this paper’s score.
- Step 1: Give yourself +2 marks for every correct answer.
- Step 2: Give yourself -0.66 marks for every wrong answer.
- Step 3: Give yourself 0 marks for any question you did not attempt.
- Step 4: Add up all the marks to get your final score.
How Cut Off Marks are Calculated in UPSC Prelims
The cut-off is the minimum score you need to qualify for the UPSC Mains exam. You cannot calculate the cut-off yourself before the results.
UPSC decides the cut-off every year based on a few things:
- Number of Vacancies: How many open positions are there for the year.
- Difficulty of the Exam: If the paper is very hard, the cut-off usually goes down. If it’s easy, it goes up.
- Number of Candidates: How many students appeared for the exam.
- Performance of Candidates: The average score of all the students who took the test.
The cut-off is announced by UPSC along with the Prelims result.
How is UPSC Prelims Marks Calculated
This is just another way of asking the main question. The calculation is fixed and based on the official UPSC exam pattern.
- Positive Marking: +2 for each correct answer in GS Paper-I.
- Negative Marking: -0.66 for each wrong answer in GS Paper-I.
- Final Score: Add all your positive marks and subtract all your negative marks.
How Negative Marking is Calculated in UPSC
The rule is simple: 1/3rd of the marks assigned to a question will be deducted for a wrong answer.
- Since a GS Paper-I question is for 2 marks, the penalty is
, which is usually taken as 0.66.
- Since a CSAT Paper-II question is for 2.5 marks, the penalty is
, which is usually taken as 0.83.
How to Calculate 1/3 Negative Marking in UPSC
Let’s make the 1/3 rule very clear with an example.
Imagine a test where each question is worth 3 marks. The 1/3 negative marking would be exactly 1 mark deducted for a wrong answer.
In UPSC Prelims GS Paper-I, a question is worth 2 marks.
- So, the 1/3 negative marking is:
marks.
- So, for every wrong answer, you lose 0.66 marks.
How to Calculate UPSC Marks
This guide focuses on the Preliminary Exam. The calculation for the Mains exam is different because it has descriptive (written) answers, and there is no negative marking there. For Prelims, always use the formula mentioned above.
How to Calculate UPSC Pre Marks
“Pre” is short for Preliminary exam. The method is the same as explained above. Use the formula for GS Paper-I and make sure you qualify in CSAT.
How Does Cutoff Marks Calculated in UPSC
UPSC does not share the exact formula they use to decide the cut-off. It is an internal process based on the factors mentioned earlier (vacancies, difficulty level, etc.). After everyone’s marks are calculated, UPSC arranges them from highest to lowest and decides a minimum score (the cut-off) to select the required number of candidates for the Mains exam.
How Marks are Calculated in UPSC Prelims Score
Your final Prelims score is only your GS Paper-I score. Let’s say you score 110 in GS Paper-I and 90 in CSAT. Your Prelims score is 110. The CSAT score of 90 just means you have qualified that paper (since it’s more than 66).
How the UPSC Marks Calculated for SC/ST/OBC
The way marks are calculated is exactly the same for all candidates, no matter which category (General, EWS, OBC, SC, ST) they belong to. Everyone gets +2 for a right answer and -0.66 for a wrong answer in GS Paper-I.
The difference is in the cut-off marks. UPSC sets a separate, lower cut-off for candidates from reserved categories like SC, ST, and OBC.
How to Calculate Cut Off Marks Method for UPSC Prelims
There is no method for a student to calculate the official cut-off mark beforehand. You can only guess based on previous years’ trends and the difficulty of this year’s paper. The final cut-off is only revealed by UPSC with the results.
How to Calculate Degree Marks for UPSC
Your marks in your college degree (like B.A., B.Sc., B.Tech, etc.) are not used to calculate your UPSC score or final rank.
You only need to have a graduation degree from a recognized university to be eligible to take the exam. Whether you got 50% or 90% in college does not matter for your UPSC marks.
How to Calculate Mark of UPSC Paper 2
UPSC Paper-II, or CSAT (Civil Services Aptitude Test), is a qualifying paper.
- Total Questions: 80
- Total Marks: 200
- Marks per question:
marks
- Qualifying Marks: You need to score at least 33%, which is
marks.
Your goal is simply to score 66 marks or higher. These marks are not added to the final prelims score for merit ranking.
How to Calculate Marks for CSAT Paper 2 UPSC
To calculate your exact CSAT score, you can use this formula:
CSAT Score = (Number of Correct Answers × 2.5) – (Number of Wrong Answers × 0.83)
Example:
- Correct Answers: 40
- Wrong Answers: 12
- Marks for correct answers:
- Marks deducted for wrong answers:
- Your Final CSAT Score:
Since 90.04 is greater than 66, you have qualified CSAT.
How to Calculate UPSC Marks When There are Wrong Questions
Sometimes, UPSC might make a mistake in the question paper. For example, a question might have no correct option or have a printing error.
In such cases, UPSC usually cancels the question. This means the question is removed from the exam for everyone. It is not evaluated, so it doesn’t give you any positive or negative marks. It’s as if the question never existed in the paper.
How to Calculate UPSC Prelims Marks 2016
The method for calculating marks in 2016 was the same as it is today. The pattern of negative marking (1/3rd penalty) has been consistent for many years. So, you can use the same formula mentioned at the top to calculate marks for any recent year’s paper.
How UPSC Calculate Rank When Same Marks
This situation, known as a “tie,” is handled in the final merit list (after Mains and Interview), not in the Prelims. In Prelims, all candidates who score the same mark at the cut-off level qualify.
For the final rank, if two candidates have the same total marks, UPSC uses a tie-breaking formula:
- Marks in the Compulsory Papers (like Essay, GS papers) and the Interview are added. The candidate with higher marks gets a better rank.
- If the tie is still not broken, the older candidate is given a higher rank.
How UPSC CSAT Marks Calculated
As explained before, CSAT marks are calculated based on your correct and incorrect answers, but their only purpose is to see if you have crossed the 33% (66 marks) qualifying threshold. They are not used for creating the merit list for the Mains exam.
