Take it step by step
- Enter total, correct and wrong question counts. They must be non-negative whole numbers and correct plus wrong cannot exceed total.
- Enter the positive marks and penalty as non-negative amounts. If the penalty is one-third of two marks, use the corresponding supplied fraction value and understand decimal precision.
- Calculate and read the formula, unanswered count and maximum. Use separate calculations when sections have different marking rules.
- Keep normalization, cutoffs and selection predictions separate. Raw arithmetic does not establish a rank or a qualifying result.
A situation to try.
For 100 questions, 60 correct, 20 wrong, two marks per correct answer and a 0.5 penalty, the supplied raw score is 60×2−20×0.5=110. Twenty questions are unanswered.
Use the tool’s synthetic example first where available. The example here explains a decision; it is not a reported benchmark result.
Before you call it done.
- Counts reconcile with total.
- Penalty is entered as a positive amount.
- Section-specific rules are not mixed.
Know the limits.
JavaScript decimal arithmetic has finite precision. The displayed raw calculation does not implement examination-specific rounding, normalization or qualifying conditions.
This tool’s current boundary: No normalization, cutoff or selection prediction. Different marking sections must be calculated separately.

Choose the right tool for this step.
Negative marking calculator
Calculate a score from question counts and the marking rule you supply.
On your deviceWhy use it: Use correct answers multiplied by positive marks minus wrong answers multiplied by the stated penalty. Unanswered questions remain separate.
Before you start: Read the current tool boundary and inspect your own result.
Private application tracker
Track real applications, stages and next actions, then export your own records.
On your deviceWhy use it: Keep the next step organised using your supplied facts.
Before you start: Saving and model downloads are explicit; nothing is sent to employers.
