Hi

You cannot go for ob/gyn i. e Obstetrics & Gynaecology in your mbbs i. e you cannot become obstetrician-gynecologist with just mbbs degree

This is because,

To become obstetrician-gynecologist one needs to do MS i. e master of surgery /MD i. e doctor of medicine in Obstetrics & Gynaecology which are post graduate degrees which you can do after mbbs.

Here's a brief of how you can become obstetrician-gynecologist :-

* First of all you need to do mbbs.

*Admission in Mbbs is through NEET examination

* Pass your 12th with at least 50 % in aggregate of PCB ( in theory +practical) in 12th examination if you belong to general category , or at least 45% in aggregate of PCB if belongs to ph category or at least 40% in aggregate of PCB if belongs to Obc/ Sc /st to be eligible for neet.

*Appear for Neet examination and qualify it . You should try to get at least around 575-600 marks to get an mbbs seat in a government medical college if you are from general category

*Then attend counselling and then on the basis of marks or Rank obtained by you in NEET examination you will get a seat for MBBS in a medical college .

* After the completion of MBBS, you need to appear for PG entrance examination, currently, some of the PG entrance examinations include:-
-) Neet PG ,
-) AIIMS PG
-)PGIMER
-)JIPMER PG.
You can know about different PG entrance examination at
