Dear aspirant,

The rough sheets are basically for security to serve it as a backup so that it could not create any problem or technical issues when your paper is checked. For any kind of issue , it would be a kind of proof that you have solved your paper.

Hi Aspirants,

They are generally piled up at the end of examination.In case of some discrepancies or some technological problems these rough sheets serve as a backup and they help you in terms of proof and all.Generally these rough sheets are not needed since everything is computerized these days.

Hope it helps!!
