All Questions in the IIT JAM Mathematics Exam: Are they of equal marks?

Introduction:
The IIT JAM (Joint Admission Test for M.Sc.) is a national-level entrance exam conducted by the Indian Institutes of Technology (IITs) for admission to the postgraduate programs in various fields, including Mathematics. The Mathematics paper of the IIT JAM exam consists of multiple-choice questions (MCQs), multiple-select questions (MSQs), and numerical answer type (NAT) questions.

Equal Marks:
In the IIT JAM Mathematics exam, not all questions are of equal marks. The marks assigned to each question may vary based on the difficulty level and the type of question. Here's a breakdown of the different types of questions and their marking schemes:

1. Multiple-Choice Questions (MCQs):
- Each MCQ carries one or more marks (e.g., 1 mark, 2 marks, etc.).
- For every correct answer, candidates are awarded the full marks assigned to the question.
- However, for every incorrect answer, there is a negative marking scheme, which deducts a certain fraction of the marks assigned to the question. This penalty may vary for different MCQs.

2. Multiple-Select Questions (MSQs):
- Each MSQ also carries one or more marks (e.g., 2 marks, 3 marks, etc.).
- Similar to MCQs, full marks are awarded for every correct answer.
- However, there is no negative marking for incorrect answers in MSQs. Candidates are not penalized for wrong attempts.

3. Numerical Answer Type (NAT) Questions:
- NAT questions are subjective questions where candidates need to provide the numerical answer.
- Each NAT question carries one or more marks (e.g., 1 mark, 2 marks, etc.).
- There is no negative marking for NAT questions, and candidates are awarded full marks for correct answers.

Conclusion:
In summary, the marking scheme in the IIT JAM Mathematics exam is not uniform across all questions. The marks assigned to each question depend on the type of question (MCQ, MSQ, or NAT) and may vary based on the difficulty level. It is crucial for candidates to understand the marking scheme and allocate their time and effort accordingly during the exam to maximize their scores.
