Dear Student,
It's a good question that which is best B.A or BCA.
Solely it depends on your area of interest.

BCA : If you like programming or want to know more about computers about their architecture or about it's internal function, then you can persue BCA. It is a great branch for students who want to make their future in developing softwares, working on networking, providing cyber security, etc. Here you can also appear in govt.exams like SSC, UPSC, State PSC, etc. Along with that you can get high package jobs in core IT companies.
B.A : If you like Arts, Music, Painting, Society, Culture, Psychology, Politics, History, Languages, Literature ,etc, then you can persue B.A. B.A is also a great branch after 12. After B.A you can join any govt. sector jobs like IAS or IPS.
You can apply for government exams (SSC, UPSC, State PSC, etc) as well as all bank exams also.

ADVICE :  If you want to secure your future then I will suggest you to join BCA when compared with B.A. It makes you a computer expert. And I think that you are pretty much aware of the fact that our world is day by day changing and becoming digitized. In this mordern world the demand of those computers geeks and experts are more.
ALL THE BEST !!!


THANK YOU
