Hi.
Bachelors in computer science and bachelor's of science both of them are slightly different to be honest .
Both have different curriculum and also variations in examination patterns.

BCA is a course that is technological like it includes advance studies of operating system,  data networking and its also a fact that it is no less than btech. whereas BSC is theoretical course in which more emphasis is on your basic science approaches.

the BCA course is precise and more sequenced there are several job opportunities as well one can opt for with high salaries around 2-3lakhs per anum. One can opt for like data scientist, java developer.
Obviously even after bachelor's degree you can find jobs but dont expect they will go you very high amounts

Also

after bsc some courses you can opt for are

M.Sc

MCA

Management studies

Data Science

Machine understanding

So it depends upon you how you have to approach to this.
