Hi

MBBS itself is not an specialisation course, one person has to choose different branches to be able to get specialised

There is nothing like which doctor is good or expensive!

Each and every doctor work hard to come along this huge course. It depends on your interest and knowledge about which branch you should choose after MBBS. MD doctor can earn more money than an surgeon or vice versa, it depends on locality, your experience and services.

It takes time to become a successful doctor after MBBS irrespective of money.

Best of luck
