Hey there!!

Btech and BBA are two totally different fields.

Where btech guides you forth towards technical knowledge, BBA provides a touch to business accounting.

It depends on you to which field you want to go..

Both have equally bright future..

If you were not able to crack btech this year and wish to become an engineer then go for it next year. Or if you wish to have grounds in business then do BBA.

MBA is a post graduate program that enhance your knowledge and act as a top cream layer..

All the best for your future buddy :)
