Hiiii..

As you ask about the documents required for counselling .....

so first of all.. you have to mention the exam and about the college in which you want to  get admission...

but as in  any college they ask  any type of proof of Identity ..so if you have your Aadhar card ,pan card or anything else..

 if that  will be  ...there will be no use of ration card ..

All the best!!
