Dear Aspirant, if your don't want to take admission in the allotted college, you can skip the seat confirmation process. An amount of 15k as per UPSEE needs to be submitted for confirming the seat in the college allotted, so don't go further. The name will be struck off automatically. Do not participate in further rounds of choice filling, not a big deal.

So automatically the admission is cancelled and process stops.

Hope this was helpful.
