🔹 How to Calculate GATE 2025 Scores Using the Answer Key?

To calculate their probable score, candidates must compare their responses with the GATE 2025 answer key. The GATE marking scheme is as follows:

✅ Marking Scheme

Correct Answer (MCQ, MSQ, NAT): +1 or +2 marks
Negative Marking:
- 1-mark MCQs: -1/3 mark deduction for wrong answers
- 2-mark MCQs: -2/3 mark deduction for wrong answers
No Negative Marking: MSQ (Multiple Select Questions) & NAT (Numerical Answer Type)

✅ Formula to Calculate GATE Score


\text{GATE Score} = (\text{Correct Answers} \times \text{Marks per Question}) - (\text{Incorrect MCQs} \times \text{Negative Marking})

For example, if a candidate has answered 20 questions correctly (10 with 1 mark, 10 with 2 marks) and 5 MCQs incorrectly (3 of 1 mark, 2 of 2 marks), their score will be:


(10 \times 1) + (10 \times 2) - [(3 \times 1/3) + (2 \times 2/3)]

= 10 + 20 – (1 + 4/3) ]


= 30 - 5/3 \approx 28.33
