Good Evening, Congratulations on completion of your class 12th.
I would like to inform you that in future whenever you will seek a job, your job profile will be based on you post graduation degree rather than on your graduation degree.
If you think BBA MBA combination will be tough, then simply go for BCOM or BA in graduation.
After that, you can pursue MBA. Any of the above mentioned combination will have the same value.

Hey!

Take your time and think about what interests you, don't be in a hurry

If you are really interested in management go for it, and I am sure you will do it, it's not that difficult after all
It has subjects like business communication marketing a bit of maths and stats cost accounts computers, it will be interesting.

As you are in doubts it will be better for you to opt for bba over bcom if u wanna go in the field of commerce.

Good luck. Be positive.
