Distinction in marking between MCQs and NAT questions in GATE CSE

Introduction:
The Graduate Aptitude Test in Engineering (GATE) is a highly competitive examination conducted for students aspiring to pursue higher education or secure employment opportunities in the field of computer science engineering (CSE) and various other disciplines. GATE CSE question paper consists of two types of questions: Multiple Choice Questions (MCQs) and Numerical Answer Type (NAT) questions.

MCQs:
1. MCQs in GATE CSE consist of a stem (question statement) followed by four options, out of which only one option is correct.
2. Each MCQ carries either 1 or 2 marks, as specified in the question.
3. Negative marking is applicable for incorrect answers. For 1-mark MCQs, 1/3 mark is deducted for every wrong answer, and for 2-mark MCQs, 2/3 marks are deducted.
4. No negative marking is applied for unanswered or unattempted questions.
5. Each MCQ can have a single correct answer, and candidates need to select the most appropriate option.
6. The options in MCQs are designed to confuse candidates, making it important to thoroughly understand the concepts and eliminate incorrect choices.

NAT Questions:
1. NAT questions in GATE CSE do not have any options to choose from. Candidates have to enter the answer in numerical form using the virtual keypad provided.
2. Each NAT question carries either 1 or 2 marks, as specified in the question.
3. There is no negative marking for NAT questions, even if the answer is incorrect or left blank.
4. The answers to NAT questions need to be entered with the specified precision, as mentioned in the question. Rounding-off is not allowed unless explicitly mentioned.
5. The questions can have multiple correct answers, and candidates need to provide the exact numerical value as the answer.
6. The NAT questions generally require a thorough understanding of the concepts and their application, as there are no options to guide the candidates.

Conclusion:
In summary, GATE CSE question paper consists of MCQs and NAT questions. MCQs have multiple options to choose from, while NAT questions require candidates to provide the numerical answer. MCQs have negative marking for incorrect answers, whereas NAT questions do not. Understanding the marking scheme and the differences between the two question types is crucial for successful preparation and performance in the GATE CSE examination.
