Hello vijayvignaraj,

           Firstly salute for choosing medical as your profession. Medical is a course where you need be a lot more focused and its takes a very long time to complete but trust me once you get into practice there would be all butterflies around....

Well coming to the point once of you complete MBBS then you need to take  NEET PG examination which is a further step for your MASTER'S it takes around 2yrs and then later you need to takeup another examination for your specialization i.e PH.D it takes around 3yrs soo completely your

MBBS (5yrs)+MASTERS(2yrs)+PH.D(3yrs)=total 10 yrs  to complete the whole of your medical....

Don't worry by seeing the duration but you will sure enjoy your study...

All the best....
