Hi Bharath.

Hope you are doing well  in this current pandemic.

I guess you have taken the xerox copies of the original Hall Ticket. So I suggest you to take the original copy and the xerox copies, so that you can show those to the concerned officers and explain the reason to them.

So carry all the necessary documents with the original and xerox copies of the KCET Examination hall ticket. That would be enough.

You can go through this link to get more information about the KCET Counselling:

If you have any more doubts you can ask.

BEST OF LUCK!!!
