Dear Sir / Ma'm, in all the counsellings all over India, be it All India Quota counselling or the State counselling, you should always carry your original certificates along with atleast two self-attested zerox copies of the same. Original certificates will be seen by the officials and they will keep the zerox and return the originals to you during the document verification.

Hello Rakesh

I would like to tell you that in any counselling procedure when you will be alloted a college for admission then next step is document verification there you need to have every document original as well as one set of self attested photocopy of originals,so keep your documents ready before you are asked for admission reporting. 

Good luck for your counselling procedure!

Feel free to ask if you have any further queries.
