Is it possible to change my college under Visvesvariah Technological University (VTU)?

It is absolutely possible to change your for the second and third year for some branch. It is possible for the 4th year too for non-autonomous colleges. The process is discussed below.

• Approach both colleges (the one you are currently in and the one you want to go to) registrars/clerical heads.
• If the college you want to go to has a vacancy you can change.
• You will need to get N.O.C from both colleges.
• You also need to go to the VTU campus, Belagavi with N.O.C, handwritten letter, and 2500 INR DD addressing the registrar. Collect your N.O.C. 
• Take all your N.O.C to the college you want to attend and they will provide you with further details on the admission procedure.

Note that you will need to do all these within 15 days from the result announcement date.
