You should always choose the course according to your interest and skill and which type of job you want to do in future.

If you are not interested in doing MBA course after your BBA then you can go for Bank exams, Defence exams, Civil Services exams like IAS, IPS or you can go railways.

You can also go for CA. It is difficult to crack and lot of hard work is required but if you have interest you can join.

Good luck!!
