M.A

If you intend to come back to India after doing your Masters in US then it is better that you pursue the said course in India itself as it will give you better exposure to the Indian context of business, moreover you will have the advantage of internship & campus placement as well.

For MA, you need to complete 10+2+3 and after that you are eligible for MA.

Yes, you can apply for MA in the same university. Don't worry you will get admission. Good luck.

Hi,It is a common paper for TISSNET. You can fill in the form with MBA or MA, whichever programme you want. Yes, the paper does consist of Mathematics, but basic Maths would be there till class 10th.
