Exam Score & Negative Marking Calculator
Estimate a raw score using the marking scheme in your official notification. Enter the question counts and marks yourself.
How the calculation works
Raw score = correct answers × marks per correct answer − incorrect answers × deduction per incorrect answer. Unattempted questions receive zero in this calculator. It supports one uniform marking scheme at a time.
For example, with 50 questions, 40 correct answers, 3 incorrect answers, 2 marks per correct answer and a deduction of 1 ÷ 3 mark, the estimate is 79 out of 100; 7 questions are unattempted. The example does not describe a particular recruitment.
Scores are displayed to two decimal places. A negative result is kept; the calculator does not impose a minimum score that your notice may not specify.
Before you use this tool
Does this predict selection or an official score?
No. It does not apply normalisation, percentile calculations, cut-offs, section weights, bonus marks or dropped-question rules. Follow the authority’s final marking instructions.
Can I use it for papers with different section rules?
Calculate each uniform section separately. Do not combine question counts under one marking scheme if the sections award or deduct different marks.
Are my answers stored or uploaded?
No answer sheet is requested. The counts and calculation stay on the page and are not uploaded or saved.
