Hi Aspirant,

Every counselling follows certain norms like when you get a college you either have to go for an upgradation round or lock your choices unless its the last rounds.For last rounds you have to choose without leaving any options.However if you have gone for upgradation but failed to get any seat in the next round then the college in which you have got your seat previously gets retained.So dont need to worry you have your previous college seat until you get any new college in the third round.

Hope it helps!!
