Hello 

Both bba and b.com can be helpful in doing MBA.

If you are interested in doing MBA in finance, marketing and banking then doing b.com is more preferable.

With bba you can get practical exposure along with studying.

Thank you 

Hello Bhishm,

The basic eligibilty for CAT is any bachelors degree, so it doesn't matter what you take.

For being technically sound, it is better to choose BBA than B.Com.

All the best!
