Introduction
The Civil Services Examination conducted by the UPSC is one of the toughest exams. Securing good marks in the preliminary round is mandatory to qualify for the mains. Many students find the papers hard, but UPSC prelims negative marking makes it even tougher. If you want to clear the first hurdle, you must understand how to calculate UPSC prelims score accurately. Let us look at the exact UPSC prelims negative marking formula to count your final marks easily.
Why Is UPSC Prelims Negative Marking Important?
Every UPSC examinee must be careful about negative marking. If you do not pay attention, you might score very poor marks. You will lose your chance to sit for the mains exam.
Here is why negative marking changes everything:
- Deduction on wrong answers: Every wrong answer eats up the marks you earned from correct answers.
- No penalty for blank answers: If you leave a question unanswered, you lose zero marks.
- Accuracy beats speed: It is better to leave a tricky question blank than to guess blindly and lose points.
- Answer key evaluation: Using a reliable UPSC prelims answer key evaluation method helps you know your rank early.
IAS Prelims Marking Scheme for GS Paper 1
General Studies Paper 1 is the first exam you take on the big day. Your cutoff score depends entirely on this paper. Therefore, you must learn the exact IAS prelims marking scheme for General Studies Paper 1 to avoid mistakes.
Key Rules for GS Paper 1:
- The paper contains exactly 100 questions.
- The total weightage of the paper is 200 marks.
- You get 2 hours to finish all 100 questions.
- Every correct answer gives you exactly 2 marks.
- Every wrong answer costs you 0.66 marks.
Step-by-Step Marks Calculation for Paper 1:
- Count the total number of questions you attempted.
- Separate them into correct answers and wrong answers.
- Multiply your correct answers by 2 to get your raw positive score.
- Multiply your wrong answers by 0.66 to get your total penalty.
- Subtract the penalty from your positive score to get the final Paper 1 marks.
Example: Imagine you choose to answer all 100 questions. You get 80 answers right and 20 answers wrong.
- Positive Marks: $80 \times 2 = 160\text{ marks}$
- Negative Marks: $20 \times 0.66 = 13.2\text{ marks}$
- Final Score: $160 – 13.2 = 146.8\text{ marks}$
