Marking Scheme for Numerical Answer Type (NAT) questions in IIT JAM Mathematics Paper

The IIT JAM (Joint Admission Test for M.Sc.) is an entrance exam conducted for admission to various postgraduate programs in science at the Indian Institutes of Technology (IITs) and other participating institutes. The Mathematics paper of JAM consists of Numerical Answer Type (NAT) questions, where candidates have to enter the numerical value of the answer using the virtual numeric keypad provided on the screen. Here is the marking scheme for NAT questions in the IIT JAM Mathematics Paper:

1. No Negative Marking:
- The NAT questions in the IIT JAM Mathematics Paper do not have any negative marking.
- Candidates will not lose any marks for incorrect answers or unanswered questions.
- This encourages candidates to attempt all the NAT questions without any fear of negative marking.

2. Partial Marks:
- Depending on the question, partial marks may be awarded for a partially correct answer.
- The partial marks are decided based on the nature of the question and the specific instructions given in the question itself.
- The exact marking scheme for each NAT question is mentioned in the question paper.

3. Precision and Rounding off:
- The answer to the NAT questions should be entered with the correct precision as mentioned in the question.
- If the question specifies a particular decimal place or significant figures, the answer should be entered accordingly.
- Rounding off the answer beyond the specified precision may lead to incorrect evaluation.
- It is crucial to read the question and accompanying instructions carefully to ensure the correct precision and rounding off.

4. Units:
- In some questions, the answer may require units to be mentioned along with the numerical value.
- Candidates should pay attention to the units mentioned in the question and provide the answer with the correct unit.
- Omitting or incorrectly mentioning the units may result in a deduction of marks.

It is important for candidates to practice solving numerical problems with precision and accuracy to perform well in the NAT questions of the IIT JAM Mathematics Paper. Proper understanding of the marking scheme and following the instructions provided in the question paper will help candidates maximize their scores in the exam.
