Dear,
I'll suggest you to go to your interest.like if you're interested in BBA (as you said to go for MBA) or if you're interested in CA/CS you can go for this only as CA/CS are post graduate degrees.
Remember BBA/MBA from a well reputated college and CA/CS particularly both are to be focused seperately.!

Normally students go for MBA after BBA. Since you are looking something different my suggestions are:
- Go for Bank test and get into a bank for job
- If you want to study then you can go for CA/CS
Or even Mcom

Hello Vaibhav. Taking a drop won't be a good idea. If you can get admission in a good college in b.tech, take that. If not, take admission in BBA again in a good college. As much as possible, avoid a gap between studies as it will be difficult to justify yourself in future for this gap.
