Mbbs is of 4.5 years course. Which includes 1 year compulsory rotarty internship. Also in some states there is criteria of bond like that of rural postings, which increases the duration by 1-3 years depending upon the respective state..

Hope you understood.

Good luck..

Dear Aishwarya, it's actually a course of 5 and half years including 1 year of internship in which you have to serve the same hospital of the college. They are broadly divided into 3 terms. You'll get to know more once you get through the exams. Dont worry.
