Yes, you can change your college in the spot round. . And there is a chance that either you will be getting a better college or a worse college then previously allotted college.. .For spot counselling you must carry a DD Of about 5000..for admission and if you like the college you can take admission in it.. 

Hi Nikita!

Yes, your college can be changed in the spot round but it depends on sheer luck and the number of available seats at that time. If, by chance, your college is not upgraded, don't get disheartened, Sirifort institute of management is also a good college. 

Best of luck!
