Hi, See I would like to be clear about what upgrading will mean here. If you wish for a seat that you have filled in as a higher choice, then please pay the fees, check willingness online after payment (there is a tab if you login) and give floating option. This is what should be done.

However some students wish to change their choices which is not possible for now but can be done in the second round. The catch there is that all good seats may have gone in the first round.
