Hello dear aspirant…

Hope you are doing well..

in the counselling rounds of guru gobind singh indraprastha university , when you get a college.. they give you two choices.. either to float or to freeze the college that you got. If you choose float then you can change the college in further counselling rounds but in case you choose freeze then you can not change the college.
hope this helps

Please ask if you have any more queries

All the best for your future!!!
