ECAT Negative Marking Calculator

How to calculate your ECAT score

1. The calculator is pre-set for ECAT: 100 questions, 4 marks per correct answer, and 1 mark deducted per wrong answer.
2. Enter how many questions you answered correctly.
3. Enter how many you answered wrongly.
4. Your ECAT score out of 400 and your percentage appear instantly, with your accuracy, the number of unattempted questions, and the marks you lost to negative marking.
5. If you are scoring a different test, change the numbers: the “Marks per correct answer” and “Negative marking” fields adapt the calculator to NUST NET, JEE, NEET, CSS or NTS.

How ECAT scoring works

ECAT is the entry test for engineering universities in Punjab, run by UET Lahore. The paper has 100 multiple-choice questions, each worth 4 marks, for a total of 400 marks — and unlike MDCAT, ECAT does have negative marking: every wrong answer deducts 1 mark. Unattempted questions score zero. So your score is (correct × 4) − (wrong × 1).

Worked example: you answer 70 correctly, 20 wrongly and leave 10 unattempted. Your score is 70 × 4 − 20 × 1 = 280 − 20 = 260 out of 400, which is 65%. The 20 wrong answers cost you 20 marks — the same as five correct answers. That is the price of guessing: a wrong answer does not just score zero, it actively takes marks away. Note that a correct answer is worth four times a wrong answer's penalty, so the maths still rewards you for attempting a question you can narrow down — but not for blind guessing on questions you know nothing about.

Your ECAT score is combined with your academic marks for the final merit. The usual weighting for UET admissions is 30% ECAT, 70% FSc (with Matric counted inside the academic part through the FSc formula) — confirm the current year's exact formula from UET, because it is set year by year. Either way, ECAT is the smaller share, so a strong FSc can carry a weaker ECAT, but a strong ECAT is what separates candidates with similar FSc marks.

Common uses

The main use is scoring ECAT practice tests and past papers: solve a full 100-question paper under the real 100-minute time limit, enter your correct and wrong counts here, and you get your score out of 400 exactly as UET would calculate it. Tracking that score across several practice papers shows whether your preparation is actually improving, and which subjects are costing you marks.

Students also use it right after the real test, once the answer key is out, to estimate their score before the official result — and then to work out their aggregate and compare it with last year's closing merit for their target discipline, whether that is Electrical, Mechanical, Civil or Computer Science.

Tips

Because a wrong answer costs 1 mark and a correct one earns 4, the rule for ECAT is simple: attempt a question if you can eliminate at least one wrong option, and skip it if you cannot. An educated guess between two options is worth it; a blind guess among four options usually is not. This is the opposite of MDCAT, where there is no negative marking and you should attempt everything — do not mix the two strategies up.

Watch your accuracy, not just your total: the calculator shows both. If your accuracy is below 70%, you are losing too many marks to negative marking, and the fix is not more practice papers — it is going back to the textbook for the topics where you guess most. Speed matters too: 100 questions in 100 minutes leaves one minute per question, so practise with a timer and learn to move on from a question that is eating your time.
