Yes you heard right IIM Calcutta is known for Finance. However you can not really differentiate between IIM A and IIM C. The internship in Finance is likely to help you.

All the best!

See if you want to do MBA in finance then all the 3 top IIMs IIM A, B, C are the best choice. Among them as you have heard it's correct IIM C has a upper hand.in finance it is better than IIM A and B. After this you can continue with the other old IIMs i.e. IIM L, K, I.

For getting in on top IIMs you need to have a good academic records because the aggregate score to call students for interview is composite of various parameters like 10th, 12th, graduation marks, work experience, engineer or non engineer, gender.

For General category students who are engineers seeing from.the last few years trend needs to score above 99.67 percentile in order to get a call for interview and WSAT round. But as you have done BBA not only you will get extra marks in aggregate score but you will also get a call for interview at a little lower percentile. This is done by college to promote diversity in their college.

If you have a good academic records then you can expect to get a call with 99+ percentile. But still I will recommend you to aim for a very high percentile in order to convert your call.

If you are giving CAT exam this time then brush up with your basics and give lots of mock test and analyse them which will help you in overcoming your mistakes and come up with a strategy to attempt your paper which will definitely help you in improving your marks and percentile.

All the best for your preparations and exam!!
