Hello Student

As you have  your seat in round 3 and alloted a college but you have not accept it even you are allowed for spot round counselling and if you allotted seat in spot round then it will not affected for your nonaccepting seat allotment in the round 3 . Get normally according to the merit for the seat allotment in spot round. There is no  negative result for your prior grounds not accepting . Spot round and go for admission.in alloted seat in spot round.

Hope this helps.
