Hello Rocky D

hope you are doing fine and great . As per your query , I would like to inform you that if you are planning to exit from a course suppose btech and start another course ,then you dont have need to pay fees of remaining years you can easily do that . But if you are planning to change the college and take admission in some other college in 2nd year,then you will need a NOC(no objection certificate) which is only provided to you if will pay the remaining years fee

Hope you found this answer helpful. Good luck for your future
