Haii.,

As you must know BCA is computer application programme where students deals with software programming and also web developer opportunities but the B.tech CSE students get more opportunities than BCA students.

About doing master's then it depends on students interest as both the courses have high scope in today's world. If you want to be a web developer and want to pursue your career in software department then MCA is good choice as this degree offers jobs in big IT companies.

In case of MBA it doesn't deal with software programming as it deals more with business management issues and this degree holders are growing world wide greatly with great career opportunities. The scope with MBA Is much more and career oriented.

Hope this information is useful to you

All the best
