MCQ Test Score Calculator
Calculate your true test score with negative marking. Enter your correct, wrong, and skipped counts to get your raw score, net score after deductions, percentage, grade band, and what-if scenarios.
What-if scenarios
How your score would change under different outcomes. Useful before deciding whether to attempt more questions.

How to read the result
- Raw score = correct answers × marks per correct answer. This is what you earned before any penalty.
- Net score = raw score − (wrong answers × negative marking). Skipped questions change nothing.
- Percentage = (net score ÷ maximum possible score) × 100. Maximum = total questions × marks per correct answer.
- Grade band: 90+ = A1, 80–89 = A, 70–79 = B, 60–69 = C, 50–59 = D, 40–49 = E, below 40 = Fail.
- Check the what-if table: if guessing more would still raise your net score, attempting is worth the risk.
Understanding negative marking
Negative marking punishes random guessing. A wrong answer costs you a fraction of a mark — commonly 0.25 marks per wrong answer when a correct answer is worth 1 mark (the 1/4 rule used in many competitive exams).
The break-even rule: with 4 options and 0.25 negative marking, guessing after eliminating one option is statistically neutral; eliminating two or more makes guessing profitable. Blind guessing on every unknown question loses marks on average.
This calculator shows the true net score, including negative values, so you see exactly how much the penalties cost you.
Frequently asked questions
How does negative marking work?
Each wrong answer subtracts a fixed number of marks from your raw score. Net score = (correct x marks per question) - (wrong x negative marks per question). Skipped questions add and subtract nothing. A common scheme is 1 mark for a correct answer and 0.25 deducted for a wrong one.
Should I guess an answer if I am not sure?
Guess only when you can eliminate at least one option. With 0.25 negative marking and 4 options, a random guess breaks even only if you can rule out one choice. If you cannot eliminate anything, skipping protects your score.
How is the percentage calculated with negative marking?
Percentage = (net score / maximum possible score) x 100. Maximum score = total questions x marks per correct answer. Because wrong answers reduce the net score, the percentage can drop well below your raw correct percentage.
Can my net score be negative?
Yes. If you get many answers wrong with negative marking on, the deductions can exceed your raw score. Most test makers floor the final score at zero, but this calculator shows the true negative value so you see the full effect.
