Exam Score Calculator
Enter correct and wrong answers to get your raw score under the exam’s marking scheme, with the marks lost to negative marking and your accuracy.
Marking scheme
Section B numerical questions have no negative marks in recent papers. Use the custom option to model them separately. Confirm the scheme in the official notice for your exam year.
Your attempt
This gives your raw score only. Ranks, percentiles and cut-offs depend on how everyone else performs and on normalisation, so they are published by the exam body after the exam.
How to use the Exam Score Calculator
- Choose an exam to load its marking scheme, or edit the marks for correct and wrong answers yourself.
- Enter how many answers you got right and how many wrong.
- Read your raw score, the marks lost to negative marking, the percentage of the maximum, and your accuracy on the questions you attempted.
Questions about the Exam Score Calculator
Does this show my rank or percentile?
No. Rank and percentile depend on how every other candidate performed, and some exams normalise scores. The exam body publishes them after the exam.
Is the marking scheme always right?
It is the usual scheme for the exam, but schemes change between years. Check the official notice for your exam year, and edit the marks above if it differs.
How is accuracy calculated?
Correct answers divided by the questions you attempted (correct plus wrong), as a percentage. Questions you left blank are not counted.
Is my information saved or sent anywhere?
No. The tool runs in your browser and the numbers you type are not sent to our servers.
Use the result as a starting point for questions.
A shortlist or estimate can help you decide what to investigate next.
What to know
