Hello Yash,
BBA and B.Tech are undergraduate courses in different streams. BBA is in commerce stream while B.Tech is in science stream.
Choosing a course would depend on what you want to pursue as a career. You should choose the course towards which you are more inclined.
So first select the stream you want to work in and then you can select your undergraduate course.
Hope this helps.
All the best!
