Good Afternoon

It is totally depends on your interest, I think BCA is better than Bcs, because:

BCS - Bachelor of Science ( Computer Science ) has a curriculum infused with Calculus, Business maths and Technical ( Web development + Software development + Networking + Operating Systems ). If you want to get into any of the things I have mentioned in between the brackets or something else that is related to programming or technical background, then BCS is better for you. By choosing BCS you are committing to a technical profile during placements.

BCA - Bachelor of Computer Applications has a curriculum infused with Management + Business maths + Technical ( Web development + Programming languages ). If you are interested in management as well as want to be loosely connected to technical areas of IT, then BCA is better for you.

Now, you can choose which one is better for you.
