Hello aspirant
Hope you are doing well.

Bonds depends upon in which state you are taking admission and in which college you are taking admission. Because bond amount changes from state to state and college to college.
Basically there are two types of bonds in Mbbs colleges:-

Service bond:- You have to serve in that state's rural areas for some duration as mentioned in your bond papers. If you don't want to do it, you can leave it by paying the bond money which is usually from 1 lakh to 10 lakhs.

Seat leaving bond:- This is the bond which you have to pay if you leave seat in between your mbbs course. Otherwise they will not give you your original documents.
