Dear Student,

You can't chance the course or branch once you have completed your registration process whether you have submitted any fee or not, one thing you do is to withdraw from the seat so they will refund your money but they cannot change your course from other as you have participated for the particular course.

Other option is for you is that withdraw your seat within 15 days of admission so they refund your 100% money now you can take direct admission in another course, by the direct mode of admission they may ask you for the money in the name of donation.

Best of Luck!!!
