Answer #1

Data processing strategies that I would use would be:-

-> I would release the result with the sheet number, because every student signs in the attendance sheet with their sheet number,thereby the sheet number would be matched with corresponding roll no./name and result will be given appropriately.

->I would use online sources-websites - in order to display some portion of the paper in the form of images, so that the concerned students can then contact the undersigned(as per the website), and thereby the result would be displayed with respective roll no/names.

->I would be display the result of all the students who provided the identification information and leave out the result of those who didn’t , simultaneously releasing the notice for the latter to come and identify the paper with proof of their handwriting and admit card. After identification Inwoukd release the correct result with respective identification information.
