Hi,

In my opinion Bsc in Computer Science is way more harder.

B Sc (CS) is more concept-oriented while BCA is application-oriented. However BCA and B Sc (CS) both is useful for students. The BCA course will teach you about current techniques and applications, giving you a basic idea of the programming languages currently used. But the BCA course will not give you a deep ideological understanding. B Sc computer science is more concept-oriented. the course will not give much importance to current technologies and applications. Candidates studying arts, commerce or science can join BCA as it is application-oriented. But intermediate certificate with mathematics is mandatory for studying B Sc computer science.

Unlike BCA, this course is more concept-oriented. It will teach you the basic concepts of computer science and give you a strong academic basis in computer science. It does not emphasize the techniques currently used that can quickly become outdated. A strong understanding of the basic concepts will help you learn new things easily where a BCA graduate can struggle. A good understanding of mathematics is essential at the intermediate level. The subjects studied include programming concepts, disk operations and control structures.

Hope this helps.

Good luck.
