Hello Madhu,

First of all congratulations on your admission, as I am guessing because of your question.

Coming to your question "in person round" means a counselling just like any other. They will call you, you have to go with your parents, DD. The students will have to stand in a line according to their rank and they will be given seats as per their preferences and availability of the seats. 

When your turn will come, you can decide which one you want to take, keeping in mind the availability

Availability of seats will also be displayed on the screen.

Hope this helps. All the very best.
