B.Com

Just go and register for XIMB exam and if you are late then just go for preparation.

maths not compulsory for pursuing B.com but you have good knowledge in accountings.This is main subject for 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.
