Formulas used
Marks per correct answer = Maximum Marks ÷ Total Questions
Net Score = Correct × Marks per Correct − Wrong × Marks per Correct × Ratio
Correct = Attempted − Wrong, and Unattempted = Total − Attempted
Accuracy = Correct ÷ Attempted × 100
Break-even accuracy = Ratio ÷ (1 + Ratio) × 100
Example
| Total | Max marks | Attempted | Wrong | Ratio | Net score | Accuracy | Break-even |
|---|---|---|---|---|---|---|---|
| 100 | 200 | 85 | 20 | 1/3 | 116.67 | 76.47% | 25% |
Here 85 attempted minus 20 wrong leaves 65 correct. Each question is worth 2 marks, so the score is (65 × 2) − (20 × 2 × 1/3) = 130 − 13.33 = 116.67 out of 200.
What is break-even accuracy?
If you are not sure about an answer, should you guess? Break-even accuracy answers that. With 1/3 negative marking you need about 25% of your attempts to be right just to avoid losing marks, and with 1/4 marking you need 20%. If you can eliminate options and push your odds above that line, attempting the question has a positive expected return.
Why track marks per attempt?
Two students can have the same score with very different attempts. Marks per attempt shows how efficiently you convert attempts into marks. Comparing it across mock tests tells you whether you are becoming more accurate or just attempting more.
Frequently asked questions
How is the net score calculated with negative marking?
Net Score = (Correct Answers × Marks per Question) − (Wrong Answers × Marks per Question × Negative Marking Ratio). Unattempted questions score zero.
What is the negative marking ratio?
It is the fraction of a question's marks deducted for each wrong answer. For example, 1/3 means a question worth 2 marks costs 0.67 marks when answered wrongly.
What is break-even accuracy?
It is the minimum share of your attempts that must be correct for guessing to stop costing you marks. It equals ratio ÷ (1 + ratio): 25% for 1/3 and 20% for 1/4 negative marking.
What does marks per attempt mean?
It is your net score divided by the number of questions you attempted. A higher value means each attempt is earning you more.
Is the negative marking ratio the same for every exam?
No. It differs between exams, papers and years. The preset buttons are quick starting points, so always confirm the ratio in your official notification.
