According to me Goenka College of Commerce and business administration in Kolkata is most suitable for doing B.Com then Saint Xavier's College because Goenka College of Commerce and business administration in Kolkata is ranked 11 all over India in business schools.
The fee structure of both of these colleges is about same which is 13500 year.

Sorry to disappoint you my friend but it won't help much.
First of all for getting B Schools outside India you need minimum experience of around 5 years. Foreign B-Schools don't accept freshers. So first look into that. CFA (Chartered Financial Analyst) is certifications for those who are looking to get into money/asset management. If you are looking to work as an equity research analyst of portfolio manager and other such jobs then CFA can help. But again there are 3 levels of CFA. For it to be of any use you need to clear at least two levels then only you would have enough knowledge to work as an equity research analyst or other such jobs. So CFA alone won't help.
If you are already in finance sector and trying to change job or climb up the ladder then it may be a bit helpful. They will give lot of experience to your job experience as such. So do thorough research of requirements of the top B-schools and then make a well informed decision. There is no point doing CFA just for sake of adding something to your resume.

Yes, it increases your chances but it is not necessary.
So, why do CFA or FRM? These are courses for individuals interested in specific fields. CFA (Chartered Financial Analyst) is for the ones who want to go in money/asset management. Those interested in equity research and analysis finds this course interesting. FRM (Financial Risk Management) is for those interested in risk management of various investments. So pursue these courses only if you want to go into that particular field and are genuinely interested. CFA takes almost one year for each level. There are three such levels. Only having level one will not help much for your career. During the interviews for admission it will surely sow your interest in finance as such. For CFA you need to put in lots of hours of study, so if you are not interested don't do it. Most of the students entering IIMs don't have a CFA. So it is okay not to have such certifications. Just go through the portions of the exam and see if you are interested.
