Degree

Dear student,
For MBA in international business, you should go for BBA in your Bachelors. There are many colleges in India which provides BBA with specialisation. In my known there is one university that is Lovely Professional University which provides several types of specialisation in BBA. It is one of the best private University with affordable fee in India awarded as best business school by several ranking institutions as well as from ministry of Human resource department of India. It's my advice to check at least once when you are going to take admission.

That will depend upon you, whether you want to do it or not. But to attend your CA final you have to do the articleship. But I have seen many who are completing their graduation along with CA articleship. Good luck.

Dear student, it totally depends on your choice of selection of course and the college. For a B.Com student, Banking and finance, Accountancy, investment banking, financial consultant etc. These specializations are better. But now a days in India only some of the Colleges which are providing specializations like this such as Lovely Professional University (one of the best private university for MBA course), VIT and other Central government institutions like Iims and IITs.
