Hello Guyyam

Both the streams are completely different from one another and will benefit you in their own ways

If u have a science background in 11th and 12th you can take up B.Pharma

If u have a commerce background in 11th and 12th you can take up BBA

given a option that u can take up any of them irrespective of your stream in 11th and 12th, take up the course where your interest lies. both are equally good in its own way.
