Understanding the Marking Scheme in the IIT JAM Physics Exam

The IIT JAM Physics exam follows a specific marking scheme that determines how marks are awarded for each correct and incorrect answer. Understanding the marking scheme can help you strategize your attempts and maximize your score in the exam. Here's a detailed explanation of the marking scheme and how you can plan your attempts accordingly:

1. Total Marks:
- The IIT JAM Physics exam consists of a total of 60 questions, each carrying 1 or 2 marks.
- The maximum marks for the exam are 100.

2. Multiple Choice Questions (MCQs):
- MCQs have four options, out of which only one option is correct.
- For each correct answer, you will be awarded +1 or +2 marks, depending on the question.
- For each incorrect answer, negative marking is applicable.
- For MCQs carrying 1 mark, -1/3 marks will be deducted for every incorrect answer.
- For MCQs carrying 2 marks, -2/3 marks will be deducted for every incorrect answer.
- If you choose not to attempt a question, there will be no negative marking.

3. Multiple Select Questions (MSQs):
- MSQs have four options, out of which one or more options may be correct.
- For each correct answer, you will be awarded +2 marks.
- For each incorrect answer, negative marking is applicable.
- For MSQs, there is no partial marking. You will receive full marks only if all the correct options are selected and no incorrect options are chosen.
- For MSQs, -2/3 marks will be deducted for every incorrect answer.

4. Numerical Answer Type Questions (NATs):
- NATs are not multiple-choice questions and do not have options.
- You need to enter the answer using the virtual keyboard provided.
- For each correct answer, you will be awarded +1 or +2 marks, depending on the question.
- There is no negative marking for NATs.

Strategizing Your Attempts:
- Start by attempting the questions you are confident about to secure maximum marks.
- For MCQs, make an educated guess if you are unsure, but be cautious of negative marking.
- For MSQs, attempt only if you are confident about all the correct options. Otherwise, it's better to skip.
- Utilize the virtual calculator provided in the exam for accurate calculations in NATs.
- Manage your time effectively and allocate sufficient time to attempt all the questions.
- Do not spend too much time on a single question. If you are unsure, move on to the next question and come back later if time permits.

By understanding the marking scheme and strategizing your attempts accordingly, you can improve your chances of scoring well in the IIT JAM Physics exam. Remember to practice previous years' question papers and mock tests to familiarize yourself with the exam pattern and gain confidence in your preparation.
