Hello Surbhi !!

You have to report to the college allotted in the first round of state quota counselling for verification . If you don't report to the allotted college then your participation in further rounds of state quota counselling will be cancelled . 

If you want an upgradation then simply go to the allotted college and opt for float option so that you still get a chance in the next round.

All the best.

Hope this helps.
