Hello,

Scientist means research work which comes in PhD. if you will do PhD then you will become a scientist. It is so simple to say by words but it is very hard yet a dangerous work sometimes.

It is a very long process and have to progress step by step. So for now complete your work for MBBS and prepare for it. If you complete MBBS, then rest of the higher studies will be done in its course of time.

Hope it helps!
