B.Com

PGDM from reputed institutes like IIM, XLRI etc and MBA in the second preference.

Dear Afrin
Eligibility for admission in IIFM is minimum 50% in graduation so my suggestion is check with admission counselor of college itself .he is the best person to guide you about it.
All the very best

If you work hard yes of course you can go abroad too. have faith in yourself, observe, learn, analyse and prove yourself a little different from others and nothing is impossible.

Taking coaching for CA or MBA entrance or Bank Po's.

No sorry, you need a minimum of 50%. Nowadays 50% minimum is essential for all the courses, but I suggest that if you are determined to do MBA don't give up. Do M.Com and score good and then try for MBA. Also concentrate on preparation for entrance exams. Where there is a will there is a way so all the best.

You have lots of job opportunities. Please refer this link :-

All the best.

Do MBA it is better choice for you

For admission in JBIMS you need to give entrance exam. But as per your query you haven't given any entrance exam. So I would suggest you to contact the college directly.

No, they have a BBA (Accountancy) program. for details and programs offered please visit the website. Here is the link

Though you must decide it yourself, accounts or finance such as Masters in professional accounting etc are what I would suggest. Which course you want to do must be chosen by you, take note of your career plans/interest and decide.
