If it's a written answer sheet where you answer questions in paragraphs, a misplaced roll number shouldn't affect your grade unless it obscures your actual answers.

If it's an OMR (Optical Mark Recognition) sheet where you fill in bubbles for answers, a misplaced roll number could be a bigger issue.

There is a difference between accidentally writing it in a blank space on the same page and writing it on a completely different sheet.

The best course of action is to contact your university's examination department or exam coordinator as soon as possible. Explain the situation and ask for their advice. They might have specific protocols for such situations.

If the misplaced roll number is still on the same page and doesn't interfere with the designated roll number section, it might be okay. But contacting the examination authority is still recommended for clarification.

If it's on a completely different sheet or obscures the designated roll number section, it could lead to issues with grading.

If your answer sheet has designated boxes or sections specifically for your roll number, filling them out incorrectly might cause problems.

If you haven't submitted your answer sheet yet, bring it to the attention of the invigilator (the person supervising the exam) as soon as possible. They might be able to provide instructions on how to proceed or offer a replacement answer sheet.

The invigilator might have specific instructions on how to handle the mistake, such as writing the correct roll number in the designated boxes and crossing out the incorrect ones neatly.


If the answer sheet has an open-ended space for you to write your details, including the roll number, then a slight mistake might not be a significant issue, especially if you've written the correct roll number elsewhere (like your name sheet).
