Hello Aditi

As the first round starts ; and if you will not get any seat in the first round than you have do nothing and it will automatically proceeds to next round .

And if you allot a seat in first or in next rounds than you have to go for verification and there are 3 options available .

• One in which you take that seat and terminate for further rounds
• Second - you will allot ( if possible ) seat from your choices you have filled and above in the preference from the previously one
• Third - college you get remains same but branch Can be upgrade in further round depending upon your rank.

Any other query ; you want to ask. Go ahead 

All the best.
