Which is the best option to pursue from BCA or B.Sc computer science for more placements and high packages?

The main difference between B.Sc. CS and BCA is BCS CS is concept oriented, It will teach you the Core Concept of computer Science, which will help you to learn anything new very quickly, other hand BCA is application oriented, teach current technologies, but learning new technologies or working on

If you see a placement, it all depends on your communication skills and not branch which you are selecting. But, I will suggest you to select technical stream that is B.Sc.
