Hi. According to the rules, unfortunately you will have to pay the bond in order to leave your seat in your respective medical college. This is because once you take admission and the counselling procedure is over, there is no way by which that seat can be allotted to any other candidate even if their marks were relevant enough for admission. That seat is yours for the next 5.5 years, no matter the circumstances. In order to leave the seat you will have to pay the amount which is equal to your total fees.
