Hi, After Bcom the specializations you can choose are:

1. MBA in Finance



2. MBA in Marketing



3. MBA in Human Resource



4. MBA in Banking



If the college/university provides the option of dual specialisation then you can opt dual specialisation in MBA Finance/Marketing so as to make the best use of the available job opportunities as dual specialisation helps to gather the basics of both the fields.



Hope this helps.

Good Luck.
