hey tanvu 

to be at safer side i would suggest you to take both origival and attested photocopy of your id proof. sometimes invigilator ask for both and sometime they just verify with original id proof. so it is no harm if you keep photocopy of id proof but you might face problem if they ask for photocopy. 

goodluck 

Hi Tanvu,

It is advised to take your admit card along with a xerox copy of it.

You have to also carry a valid identity proof like Aadhar card (preferably along with a xerox) and also a few photographs (4-6).

You will not be allowed to take any water bottle or pen inside as the authorities will provide you with pens.

All the best!!!

it is advised to preserve a zerox copy of your admit card. You have to take a valid identity proof (preferable along with a zerox) and also a few (4-6 passport sized photographs) along with it. You will not be allowed to take any water bottle or pen inside the examination hall, as pens will be provided by the authorities.
