Heya Vidhi !!

If you are alloted with a seat in any college in the first round itself, then you need to get your documents verified and then yoi will get your admission confirmed. 

But as per your case, you missed the document verification part due to some or other reason and still want a seat in subsequent rounds, then for the state counselling, there are like about 3 rounds and if you missed docs verification part then you need to apply again in the next rounds for getting a seat.

Hope it helped you to quench your query.  :)
