Frequently Asked Questions
Why do competitive exams use negative marking?↓
Negative marking discourages blind guessing on multiple-choice questions (MCQs), ensuring that scores accurately measure test-taker competency and conceptual understanding rather than luck.
Is it worth guessing if there is a 1/4 negative penalty?↓
Statistically, on a 4-option question with a 0.25 deduction, random guessing has an expected value of 0. However, if you can eliminate at least one or two options, your expected return turns positive.
What does the Attempt Accuracy Rate tell me?↓
Attempt accuracy measures what percentage of the questions you actually answered were correct (Correct / [Correct + Wrong]). High accuracy (above 85%) protects against score degradation from penalties.
What limitation should I keep in mind if questions carry different point values?↓
This calculator assumes standard uniform question weighting (+1 per correct question). If questions carry differing marks (e.g. 2 marks for math, 1 mark for English), multiply accordingly.
