How to Calculate Negative Marking in Ibps

Negative marking is a common feature in competitive exams like IBPS, where incorrect answers deduct a portion of the total marks. Understanding how to calculate negative marking helps candidates strategize their exam approach effectively.

What is Negative Marking?

Negative marking refers to the practice of deducting marks for incorrect answers in multiple-choice exams. This system is designed to penalize guesswork and encourage candidates to attempt all questions carefully.

In IBPS exams, negative marking is typically applied to objective-type questions where candidates must select the correct answer from multiple options. The exact penalty varies by exam and section.

How Negative Marking Works

When negative marking is applied:

Each correct answer awards full marks (usually +1 or +2 marks).
Each incorrect answer deducts a portion of the marks (typically 1/3 or 1/4 of the marks for that question).
Unanswered questions receive zero marks.

The final score is calculated by summing the marks from correct answers and subtracting the marks deducted for incorrect answers.

Calculating Negative Marking

The formula to calculate the final score with negative marking is:

Final Score = (Correct Answers × Marks per Question) - (Incorrect Answers × Negative Marks per Question)

Where:

Correct Answers - Number of questions answered correctly
Marks per Question - Marks awarded for each correct answer
Incorrect Answers - Number of questions answered incorrectly
Negative Marks per Question - Marks deducted for each incorrect answer

For example, in an exam with 100 questions where each question carries 2 marks and 1/3 mark is deducted for each incorrect answer:

Negative Marks per Question = Marks per Question ÷ 3

= 2 ÷ 3 ≈ 0.6667 marks

Example Calculation

Let's calculate the final score for a candidate who:

Answered 75 questions correctly
Answered 15 questions incorrectly
Left 10 questions unanswered

Using the same parameters as above (2 marks per question, 1/3 mark deduction):

Final Score = (75 × 2) - (15 × 0.6667)

= 150 - 10 ≈ 140 marks

This means the candidate scored 140 out of a possible 200 marks.

Frequently Asked Questions

Why is negative marking used in IBPS exams?

Negative marking discourages random guessing and encourages candidates to attempt all questions carefully. It helps maintain exam integrity and rewards thorough preparation.

How does negative marking affect the cutoff?

Negative marking can lower the cutoff score because incorrect answers reduce the total marks. Candidates need to balance speed and accuracy to maximize their scores.

Can I skip questions with negative marking?

Yes, skipping questions is a valid strategy. Unanswered questions receive zero marks, so you should only attempt questions you are confident about.

How can I prepare for negative marking?

Practice with timed mock tests, review your mistakes, and focus on high-weightage topics. This helps you identify patterns and improve your accuracy.
