Which specialisation should I opt in MBA?

Dear Dipendra Prasad, Based on your graduation, if you are from commerce and maths background, go for finance and operations. If not, go for marketing and HR. All the best.

That completely depends on you. I think in this case, you should take your interests into consideration. If you have good communication skills and love interacting with people, you should go for marketing or PR. If you are into mathematics, calculations or analyzing data, you can think about finance
