Hello,

If you are alloted seat in 1st round, then you must need to take admission in that college, after that you can opt for internal switching of branch. If you didn't take admission in 1st round, then you may lose your seat and you couldn't able to take admission later. So keep in mind to take the admission in the right time, don't wait for the second round.

All the best

Hi student

Yes, you can. If you are allotted a seat in round 1, you'll be given two options, one is to block your seat which means you are confirming your seat and the second is to upgrade which means you can wait for the 2nd or further round in order to get better college options.

All the best.
