Marking Scheme for Questions with Multiple Correct Options in IIT JAM Physics Paper

In the IIT JAM Physics paper, there are questions that have multiple correct options. These questions are designed to test the candidate's understanding and knowledge of the subject matter in a more complex manner. The marking scheme for such questions is implemented in a specific way to ensure fair evaluation and accurate scoring. Here, we will discuss the details of the marking scheme for questions with multiple correct options in the IIT JAM Physics paper.

1. Question Structure:
Questions with multiple correct options in the IIT JAM Physics paper consist of a stem (the main question) followed by a set of options (usually four) labeled as A, B, C, and D. The stem provides the context or problem statement, and the options represent possible solutions or choices.

2. Marking Scheme:
The marking scheme for questions with multiple correct options follows the principle of partial marking. Each question is assigned a total of 2 marks, which is further divided into positive and negative marks as follows:

- Positive Marks: For each correct option selected, the candidate is awarded +1 mark.
- Negative Marks: For each incorrect option selected, a penalty of -1/3 mark is deducted.

3. Scoring Method:
To calculate the final score for a question with multiple correct options, the following steps are followed:

- If all the correct options are selected and no incorrect options are chosen, the candidate is awarded the full +2 marks for that question.
- If all the correct options are selected, but the candidate also selects one or more incorrect options, the positive marks are still awarded, but the negative marks are deducted for each incorrect option selected.
- If only some of the correct options are selected and no incorrect options are chosen, the candidate is awarded +1 mark for each correct option selected.
- If incorrect options are selected, regardless of whether any correct options are selected or not, the penalty of -1/3 mark is deducted for each incorrect option.

4. No Partial Credit:
It is important to note that there is no partial credit given for partially correct answers. Each option is evaluated independently, and the candidate is awarded either the full positive mark or the negative mark for each option based on their selection.

5. Answering Strategy:
To maximize their score, candidates must carefully analyze each option and select only those options that they are confident are correct. Guesswork or random selection of options may result in negative marking, which can significantly impact the overall score.

In conclusion, the marking scheme for questions with multiple correct options in the IIT JAM Physics paper follows the principle of partial marking. Candidates are awarded positive marks for each correct option selected and penalized with negative marks for each incorrect option selected. It is essential to analyze the options carefully and select only the correct ones to avoid negative marking and maximize the overall score.
