Know All About 0.5 Negative Marking with Examples

Negative marking is a scoring system used in exams or assessments where points are deducted for incorrect answers. It aims to discourage random guessing and encourage careful thinking and accuracy. In the case of 0.5 negative marking, half a mark (0.5) is deducted for each wrong answer. Let's delve into an example to understand this concept better.


Imagine you are taking a test that consists of multiple-choice questions. The total marks for the exam are 100, and there are 100 questions. In this scenario, each correct answer carries 1 mark, while an incorrect answer leads to a deduction of 0.5 marks.

  • Correct answer: +1 mark

  • Incorrect answer: -0.5 marks

  • Unattempted question: No marks deducted

Let's consider a few scenarios:


You answer 80 questions correctly, leave 10 questions unattempted, and answer 10 questions incorrectly.


  • Correct answers: 80 * 1 = 80 marks

  • Incorrect answers: 10 * (-0.5) = -5 marks

  • Unattempted questions: 0 marks deducted

  • Total marks obtained: 80 - 5 = 75 marks

In this example, despite answering 80 questions correctly, the deduction of 0.5 marks for each incorrect answer (10 questions) results in a penalty of 5 marks. As a result, the total marks obtained are reduced to 75.

The 0.5 negative marking system highlights the significance of accuracy and discourages guesswork. It forces test-takers to carefully consider their answers and avoid randomly guessing, as incorrect responses can significantly impact their overall score.
