Hello Snehil,

If you belong to the general category ,im afraid it is very difficult to get your desired seat,however if u you belong to a reserved category ,there is a fair amount of chance that u might get either EC or CS in the 2nd extended or the casual round and not in the first and second round.

hence please do not loose hope and keep proceeding to further rounds of option entry to get your desired seat

hope it helps

thank you
