yes you can definitely go for the special round called as the spot round . The seat which you have freezed is now yours if you want to try for spot then you need to re-pay the counselling fee for spot round and thus due to the reason as yours some candidates are there who dont want the seat and thus either leave for iits nits or some more better colleges or for the spot round . So go ahead dont be tensed you will surely get a seat in spot if your rank is that much good and the seats are left.

Hey Vivek,

No worries there is a spot round counselling for the leftover seats. You can sit for that round to get a college where the seats are vacant. But in this round, you won't get a choice for your own prefered college and the brach of that college. Either of the one you can choose. you can contact the UPSEE officials to get details about the special round or spot round counselling.

Hope that helps

all the best
