What additional courses can I pursue after doing BBA?

Ideally, an MBA is the best to join the corporate sector. Other than this, you may go for PG diplomas in accounting, taxes, business laws, finance, etc. Training in commerce related to software is also possible. Choose as per your interest.

MBA/MMS/PGDM is the preferred option after BBA. If not MBA you can also opt for LLB/ CA/ CS, etc. or join some short term diplomas or certificate courses in your preferred subjects. All the best.
