What are GATE EE MCQ, MSQ and NAT Questions?

There will be 3 types of questions in the exam of GATE Electrical Engineering, ie, MCQ, MSQ, and NAT questions. Not only these questions but their answering method will also differ. Saying in a crux, where in MCQ, there are only 4 correct questions, on the other hand, MSQs will hold various correct answers. More detailed description about the GATE 2025 EE MCQ, MSQ, and NAT questions can be found below:-

Multiple Choice Questions (MCQs): In the MCQ questions, there will be 4 options, from which you will be required to choose only 1 correct answer. Please know that opting for a wrong answer will result in negative marking.
Multiple Select Questions (MSQs): These questions have several correct answers and to earn marks, you will have to select all the correct options. There will be no negative marking in the MSQs.
Numerical Answer Type Questions (NATs): These are the numerical problems that you need to solve mathematically. These questions typically have an answer in decimal form. The authority does not follow any kind of negative marking in the NATs.
