Greetings!!

Since you have already got/ allotted a seat in Karnataka State Round 1, and if you accept the seat in this case you won't be able to get a seat in the future in Round 2, Round 3.

However if you don't take the seat that has been allotted to you in Round 1 and then decide to opt in the second round, then you can participate in the counselling after round 1, otherwise you will have to take the seat that has been allotted to you in this round .

Also, once you have cancelled a seat then you can't take the same seat again thus take a prudent decision accordingly.
