GATE CSE 2027 Marking Scheme
The GATE 2027 paper has three question types: MCQ (Multiple Choice Questions), MSQ (Multiple Select Questions), and NAT (Numerical Answer Type).
- The MCQ has one correct option, the MSQ has one or more correct options, and NAT needs a numerical value.
- For a 1-mark MCQ, you lose 1/3 mark for a wrong answer, and for a 2-mark MCQ, you lose 2/3 mark for a wrong answer.
- Negative marking applies only to MCQs, while MSQ and NAT have no negative marking. There is also no partial marking in MSQ, unlike MCQs.
