BCA

Hi,
This is something you should know. Make a note of your likes, interests and career plans and you will have an answer to your question. Country choice can be narrowed down on the basis of your profile, university requirements, your budget and where you want to settle down. I believe you have posted this question earlier too.

Both BBA and BCA are equally good. BBA is a generic management degree which prepares you for supervisory jobs. Whereas, BCA is graduation degree which will provide you with the technical skills for entry-level jobs in IT industry. Both the degrees only offer entry level jobs. For meaningful career, you will have to do post-graduation in both the options. Both options give similar starting salaries. If you are technically oriented then you may opt for BCA else BBA is a better option.

BCA is a job oriented course, but it all depends on the college and placement. BCA is graduate level course so you can apply for the graduate-oriented jobs. It gives you practical knowledge. Company job is common unless you crack a government exam or you can do MCA after completing BCA and join the teaching field.

Yes, maths is necessary to pursue BCA.

BCA has a huge scope. It all depends on you, how depth knowledge you have of the domain. The average package is around 15000 per month for a fresher. Of course, pay package will increase further if you do great in your job.
