BCA is better .

As nowadays programming is evolving.

There's so much to learn.

Much development in data analytics artificial intelligence is happening.

So you can get a good job too.

Also

BSC mechatronics is not bad but it's not as good as BCA

If mechatronics interest you then go for it pursue what you like

Hi dear,

Hope you are doing well!

Now let's go through your question.

ВСА:

Syllabus of the three-year BCA course includes subjects involving computer languages, database management, operations systems, logical analysis, software

design and client server technology. Several universities offer this 3 years undergraduate course across India

Scope:

The most logical step after the BCA course is to pursue an MCA. Alternatively, you may look into jobs in the IT sector or related fields

B.SC:

It offers theoretical as well as practical knowledge about different subject areas.

These subject areas usually include any one of the main Science fields (Physics(metatronics),Chemistry, and Biology) and other fields depending on the specialisation a student opts Pursuing a BSc course is most beneficial for students who have a strong interest and background in Science and Mathematics.

The course is also beneficial for students who wish to pursue multi and inter-disciplinary science careers in future.

Thank You & All the best!
