Hi Rajneesh,
Once you are allocated a college in the allotment list then the further admission process will be completed in the college itself. No confirmation or anything will be done online.
After admission the college will ask you to select the option of freeze or float. Free exit is also there where you just do not go to the college for admission.
In any case the processes is covered by the college and not online.
I hope this information helps.
All the best.
