Hey Maya.

To become a surgeon, in India you would require a minimum of 11.5 years.

First you will have to complete your MBBS degree which will take you 5.5 years (including compulsory internship period) Then you will pursue an MS degree which will take you 3 years. After that, if you want to do further specialisation like Neurosurgery, cardio surgery etc you will pursue an MCH degree which will take you 3 years.

You can also pursue MCH directly after MBBS in Institutes which provide an MCH degree directly after MBBS. It is a 6 year degree. Pursuing MCH is optional. You can do it only if you want to specialise in some particular field. But this will increase your Career prospects, salaries, value to a great extent.

This does not include the years or time you might take for preparing for MBBS/ MS/MCH entrances. It varies from person to person.

Best of luck!
