Well , I  wil suggest to take BBA with experience as Iam also from BBA ,now currently iam studying PGDM marketing ( MBA).

I always wanted to took MBA that's why I went to BBA

See BBA- Bachelor of business administration

MBA- Masters of business administration

They both are very similar not only with name but also subjects , almost subjects i studied got repeated in MBA. like

1.principal of management

2.finacial management

3.Marketing management

4. Human resources management

5. Statistics

Most of the subjects got repeated in MBA too.so it will like continuing subjects which were studied in BBA .oh difference is subjects are narrative in BBA, where in

MBA they are a bit descriptive.

So my opinion will be choosing BBA will better to understand all subjects in MBA easily. & For better understanding of management subjects.

I think you should go to  bbA because this is related to business administration if you have further goal for MBA
