Formula Used

Attempted Questions = Correct Answers + Wrong Answers

Unattempted Questions = Total Questions − Attempted Questions

Positive Marks = Correct Answers × Marks per Correct

Negative Marks = Wrong Answers × Penalty per Wrong

Blank Question Marks = Unattempted Questions × Marks per Unattempted Question

Net Score = Positive Marks − Negative Marks + Blank Question Marks + Bonus Marks

Accuracy (%) = (Correct Answers ÷ Attempted Questions) × 100

Break-even Guess Accuracy (%) = Penalty per Wrong ÷ (Marks per Correct + Penalty per Wrong) × 100

Frequently Asked Questions

1. What does a wrong answer penalty mean?

It is the score deduction applied for each incorrect answer. Negative marking discourages blind guessing and rewards accurate attempts.

2. How is net score calculated?

Net score equals marks from correct answers minus penalties from wrong answers, plus any bonus marks and allowed marks for unattempted questions.

3. Why is break-even accuracy important?

It shows the minimum success rate needed for guessing to avoid losing marks on average. Lower actual accuracy makes random guessing risky.

4. Can I use decimal penalties like 0.25 or 0.33?

Yes. The calculator accepts decimal marking schemes, so it works for quarter-mark, one-third, and custom deduction patterns.

5. What if my exam gives bonus marks?

Enter the bonus marks in the bonus field. They are added after penalty and blank-question calculations to produce the final score.

6. Does the calculator help with target planning?

Yes. It compares your current score against a target and estimates extra correct answers needed, assuming no additional wrong attempts.

7. Why does the graph matter?

The graph visualizes how increasing wrong answers can reduce score sharply. It helps you choose a safer attempt strategy.

8. Can I save the result for revision planning?

Yes. After calculation, download the result as CSV or PDF and use it for mock-test review, coaching logs, or progress tracking.
