This is an independent tool and not an official government calculator. The marking scheme, total questions and final result are decided by the recruiting authority, so always match them with the official notification and answer key.
How to use the ADRE marks calculator
Download the official answer key after the exam and check your response sheet against it. Count how many answers are correct and how many are wrong. Questions you left blank do not need to be entered, because the tool finds them automatically by subtracting your correct and wrong answers from the total.
Next, check the marks per correct answer and the negative marks per wrong answer. The tool starts with common values, but you should change them to match the marking scheme printed in your question paper or the official notification. If you already know the expected cut-off for your category, enter it as well and the tool will tell you how far above or below it you are. Press “Calculate marks” and your estimate appears at once. As with every tool on this site, the calculation happens in your browser and your numbers are never saved or uploaded.
Formula used
The calculator uses the standard marking formula for objective exams:
Score = (Correct answers × Marks per correct answer) − (Wrong answers × Negative marks per wrong answer)
Maximum marks are the total questions multiplied by the marks per correct answer. Percentage is the score divided by the maximum marks, multiplied by 100. Accuracy is the share of attempted questions you answered correctly: correct answers divided by (correct plus wrong), multiplied by 100. Accuracy is useful because a high score with many wrong answers is riskier than the same score with fewer attempts.
| Term | Meaning |
|---|---|
| Attempted | Correct answers + wrong answers |
| Not attempted | Total questions − attempted |
| Negative marks lost | Wrong answers × negative marks per wrong answer |
Example
Imagine a paper with 100 questions, 1 mark for each correct answer and 0.25 negative marks for each wrong answer. A candidate gets 72 answers right and 16 wrong, and leaves 12 blank. The negative marking is 16 × 0.25 = 4 marks, so the score is 72 − 4 = 68 out of 100, which is 68 percent. The candidate attempted 88 questions, so accuracy is 72 ÷ 88, about 81.8 percent.
Now compare a second candidate who attempts all 100 questions, with 60 right and 40 wrong. The negative marking is 10, so the score is 50 out of 100. Even though this candidate attempted more questions, the lower accuracy of 60 percent pulled the final marks down. Examples like this show why careful guessing matters when negative marking is present.
Frequently asked questions
Does ADRE have negative marking?
This depends on the exam pattern in the official notification. If there is no negative marking, set the negative marks field to 0 and the calculator will adjust.
Is the estimated score my final result?
No. It is an estimate based on the answer key you used. Final marks can change if the authority revises the key, removes a question, or applies normalisation.
What if a question is cancelled?
Reduce the total questions by one and recount your correct and wrong answers without that question. If marks are awarded to everyone, count it as correct.
How do I use the cut-off field?
Enter last year’s cut-off or the expected cut-off for your category. The tool shows the difference so you can judge your chances. Cut-offs change every year, so treat this only as a guide.
Is my data stored?
No. The calculator runs completely in your browser and sends nothing to any server.
