Hello Aspirant,
Yes you can do so, but for this you have to apply for upgradation after the result of round 2nd so that you can get an upgraded seat in mop-up round and also note that if you have already joined the seat then also you can take part in mop-up round provided that you resign the seat before the cut-off date as decided by the competent authorities for Kerala counselling.
