Hello candidate,

The original documents are required in most of the entrance examination document verification process and in various other admission procedures, these documents are not required to be submitted but there xerox copies are submitted to the respective officials so that they can keep a proper documentation regarding your valid admission at any specific college or university. the similar words to for the caste certificate where the original caste certificate is multi checked and given back to the candidate while it's scanned copy is kept by the officials as a permanent record.

Hope you found it helpful. If you have any further questions feel free to post it here!!
