Hello,

Making a mistake in the last three digits of your roll number in your painting practical should not affect your result significantly. Examiners usually verify details using additional information like your name, school, or registration number.

Here are some points to consider :-

• If your roll number is unique enough, they might still identify your work correctly.
• Contact your school or exam authority as soon as possible to inform them of the mistake.
• They may allow corrections before finalizing results.
• Stay calm and focus on your studies for upcoming exams.
• Most likely, the issue can be resolved without affecting your marks.

Just stay calm and don't worry !
