How to calculate negative marking

Imagine you’re preparing for a competitive exam, and you’ve answered 100 questions. But wait—did you account for *negative marking*?

Every wrong answer could cost you precious points, turning confidence into confusion. Understanding how to calculate negative marking is crucial to maximize your score and avoid surprises.

In this guide, we’ll break down the process with examples, formulas, and expert strategies to help you master this skill—even if you’re a beginner!

What Is Negative Marking?

Negative marking is a scoring system where **incorrect answers deduct marks** from your total score, while unanswered questions may or may not penalize you. It’s commonly used in exams like SAT, NEET, UPSC, and GRE to discourage guesswork.

How to Calculate Negative Marking: The Formula Explained

Step 1: Know the Exam’s Marking Scheme 

Most exams follow this structure:

  • Correct answer:** +4 marks
  • Wrong answer:** -1 mark (or -0.25 to -2, depending on the exam)
  • Unanswered:** 0 marks

Step 2: Use the Negative Marking Formula 

The formula to calculate your final score is:  

\[ \text{Total Score} = (\text{Correct Answers} \times \text{Marks per Question}) – (\text{Incorrect Answers} \times \text{Negative Mark per Question}) \]

Example: 

If you answer **75 questions correctly** and **15 incorrectly** in an exam with **+4 for correct** and **-1 for wrong**:  

\[ \text{Total Score} = (75 \times 4) – (15 \times 1) = 300 – 15 = 285 \]

5 Pro Tips to Avoid Losing Marks to Negative Marking  

1. Don’t Guess Blindly:Only attempt questions you’re 50%+ confident about.

2. Practice Mock Tests: Simulate exam conditions to refine your accuracy.

3. Focus on High-Weightage Topics: Prioritize sections you’re strong in.

4. Review Past Papers: Identify patterns in negative marking schemes.

5. Time Management: Allocate time to revisit unsure answers.

FAQs About Negative Marking

1. Why do exams use negative marking?  Negative marking discourages random guessing and ensures candidates only answer questions they’re reasonably sure about. 

2. Is it better to skip a question or guess?

Skip unless you can eliminate at least 2 wrong options. For example, in a 4-option question with a -1 penalty, guessing gives you a 25% chance of gaining +4 but a 75% risk of losing -1.  

3. How is negative marking calculated in MCQ exams?  

  • Use the formula:

\[ \text{Score} = (\text{Correct} \times +4) – (\text{Wrong} \times -1) \]

4. Do all exams deduct marks for unanswered questions?  No—some exams (like JEE Main) only penalize wrong answers, not skipped ones. Always check the rules first! 

5. Can negative marking reduce my score below zero?  

Most exams set a “floor score” of 0, but policies vary. Confirm with your exam provider. 

Conclusion:

Turn Negative Marking into a Positive Strategy  Negative marking doesn’t have to be scary—it’s just math! By practicing with the formula, avoiding guesswork, and taking timed mock tests, you’ll boost both accuracy and confidence.
