Dear Kunwar, the 1 year mandatory internship is a part of MBBS course. The course is for 4 and 1/2 years and 1 year is specifically for Internship which is mandatory. You will not get your MBBS degree if you do bot complete your Internship. It's non negotiable. There is no bond but without completing the internship, it is as much as you haven't studied MBBS at all.
