Hi ,

There is no question of which Specialisation is Better. It all depends on your ambitions and personal ability.

If you got Excellent communication skills, an outgoing personality, creative, have a zeal to sell and you wanna do MBA in Marketing / opt for Jobs in Sales/Business Development/Marketing, you should go for BMS (Marketing).

If you have a flair for juggling numbers and are good at number-crunching and think you can manage the party well and wanna do MBA in Finance / opt for Jobs in Finance field as Financial Accountant/Manager then go for Specialization in Finance.

Hope this helps

Wish you luck
