Your Response Sheet Is the Most Useful Document You Will Ignore
The official answer key and your own response sheet let you compute your raw score before the result. Most candidates download both and never open them.
After most computer-based exams the conducting body publishes two things: a provisional answer key, and your own response sheet showing what you actually marked. Put them side by side and you can work out your raw score weeks before the result, decide whether an objection is worth filing, and learn something about how you sat the paper. Most candidates download both, glance at them, and close the tab.
- Raw score is (correct times marks per correct) minus (wrong times the deduction). Unattempted questions score zero.
- Count your wrong answers separately from your unattempted ones. They mean different things about the same paper.
- The objection window is short and usually carries a fee per question, so check the notice the day the key appears.
- A provisional key can change. Your score is an estimate until the final key is published.
Working out the raw score
Two numbers do it, and both are on your exam's exam pattern page: what a correct answer earns, and what a wrong one costs. Count your correct answers, multiply by the first. Count your wrong answers, multiply by the second. Subtract. Unattempted questions score zero on every scheme, so they do not enter the arithmetic at all. The one thing to be careful about is that the deduction is not the penalty: a paper awarding 4 marks and deducting 1 takes a quarter of a correct answer, the same as one awarding 1 and deducting 0.25, and understanding negative marking explains why the two look so different and are not.
Then separate the wrong from the blank
This is the part worth more than the score. A wrong answer and an unattempted one both cost you a mark you could have had, but they come from opposite mistakes. A paper full of wrong answers means you were attempting things you could not do, and the fix is to guess more carefully. A paper full of blanks means you left marks on the table, and on most schemes here that is the more expensive error, because the guessing break-even is lower than people assume. Count both before deciding which habit to change.

Read the questions you got wrong, not the score
The score tells you one number you will get officially in a few weeks anyway. The response sheet tells you which questions, in what order, and that is the part you cannot get from the result. Look for the ones you answered wrongly early in the paper, when you were fresh, because those are knowledge gaps rather than fatigue. Then look at where the blanks cluster, because a run of them together usually means you lost the clock in that section rather than that you found those questions hard. How to build an error log covers turning that into something you will actually revisit.
About the objection window
Most bodies allow candidates to challenge a provisional key inside a short window, usually with a fee for each question challenged, sometimes refunded if the challenge succeeds. The rules, the fee and the deadline differ by exam and by cycle and they are stated in the notice rather than fixed, so read the one for your exam on the day the key appears rather than trusting any summary, this one included. What is generally true: the window is measured in days, it closes on time, and a challenge needs a source rather than a disagreement.
Treat the number as provisional
A provisional key is provisional. Answers get revised, questions occasionally get dropped, and a dropped question is usually credited to everyone or removed from the total, either of which moves your score. Work out the figure, note it, and do not plan around it until the final key lands. If the estimate is close to a previous year's cut-off, remember that cut-offs move with the paper and the vacancies: understanding cut-offs and percentile covers why last year's number is a weak guide to this year's.
Where an exam on this site has published a key or response-sheet notice, it is summarised with its source on the exam updates page.

Frequently asked questions
How do I calculate my score from the response sheet?
Count your correct answers and multiply by the marks a correct answer earns. Count your wrong answers and multiply by the deduction. Subtract the second from the first. Unattempted questions score zero and do not affect the total. Both figures are on your exam's pattern page, and the deduction alone does not tell you the penalty without the marks per correct answer beside it.
What is the difference between an answer key and a response sheet?
The answer key is the conducting body's list of correct answers for the paper. The response sheet is the record of what you personally marked, question by question. You need both: the key alone tells you nothing about your paper, and the response sheet alone tells you what you chose without telling you whether it was right.
Should I challenge a question in the objection window?
Only with a source. A challenge backed by a textbook, an official document or a standard reference has a chance; a disagreement does not. Most bodies charge a fee for each question challenged, which is often refunded when the challenge succeeds, and the window is short. Read your exam's own notice for the fee, the deadline and the format, because these differ by exam and by cycle.
Is the score from a provisional key final?
No. Provisional keys get revised, and questions are sometimes dropped and either credited to every candidate or removed from the total, which changes your score either way. Treat the figure as an estimate until the final key is published, and be especially careful about it if your estimate sits near a cut-off.
