Hello,
Internship is a compulsory service to be provided by a medical graduate after completion of his/her course in the hospital affliated to their colleges.

The mbbs course is of 4.5 years with 1 year compulsory internship.

The stipend in government colleges like kgmu is around 20-30k/month while for afmc its around 60k/month.

The amount given to a person pursuing md/ms is different for different branches and for different colleges.
However it ranges around 60k-1lakh/month.
Hope this helps
