Yes, you can. Since, you are pursuing B.Sc in stats and MBA in data analytics, it would be an advantage for you.

Admission into MBA without CAT/open test will not lead you to a good college and also will not be of much utility from career perspective.

MBA is not offered in IIM-A. It offers PGPM.

For admission candidate has to pass CAT common admission test) conducted by IIM Bangalore.

You should target 99+ for IIM's. You might get a call from FMS with 97-98 percentile.

There are chances, if you are a non-engineer with a 99+ percentile. It is much more difficult, if you are an engineer as that would require a very high percentile in order to stand at par with other candidates.

It is highly unlikely to be honest. All the best anyhow.
