Marking Scheme for IIT JAM Physics Exam:

When it comes to the IIT JAM Physics exam, the marking scheme is crucial in determining the scores of the candidates. The marking scheme is designed to ensure fairness and accuracy in evaluating the performance of the candidates. However, in case of any discrepancy in the question or answer key, there are certain procedures followed to rectify the situation and maintain the integrity of the examination process.

Discrepancy in Question:

If there is a discrepancy in the question, it is usually brought to the attention of the examination authorities by the candidates or the examiners. The authorities then carefully analyze the issue and take necessary actions to resolve it. The following steps are usually followed:

1. Verification: The examination authorities verify the discrepancy in the question by comparing it with the original question paper and evaluating the concerns raised.

2. Decision-making: Based on the verification process, the authorities decide whether the question is indeed incorrect or unclear. If it is determined that the question is incorrect, then the marks for that particular question may be awarded to all the candidates, irrespective of their attempted answers. On the other hand, if the question is found to be unclear, then it may be decided to award marks to all the candidates, regardless of their answers, or the question may be deemed invalid and eliminated from the evaluation process.

2. Decision-making: Based on the verification process, the authorities decide whether the answer key is incorrect or needs revision. If it is determined that the answer key is incorrect, then the necessary adjustments are made, and the revised answer key is used for evaluating the candidates' responses.

3. Recalculation of Scores: After the revision of the answer key, the scores of all the candidates are recalculated based on the revised key.

Conclusion:

In summary, if there is a discrepancy in the question or answer key of the IIT JAM Physics exam, the examination authorities take prompt action to rectify the situation. The verification process is carried out carefully, and decisions are made to ensure fairness and accuracy in evaluating the candidates' performance. These measures help maintain the integrity of the examination process and provide a fair assessment of the candidates' abilities.
