BCA

Hi,
MCA is anyways equivalent to B.Tech. But in order to compare, the scope of either MBA or MCA is always better because these are post graduation degrees.
However, if I will come to salary and job prospects, both depend on many factors like experience, skills, location, companies, merit, etc. MCA is a technical degree and if you want to stick around technology, then it will help otherwise to get a managerial level, MBA is slightly a better choice.

I would suggest you CSE as the world is growing rapidly and so is the technology. You have completed class 12th, you can join CSE or BCA.
All the best.

They are totally opposite streams and you need to decide your area of interest between computers or public relations.

Hi,
Companies will hire you but you should have the specific reason for the discontinuation in your educational career.

Hi,
It depends on the college ranking/marks.

IT and CSE are better option than BCA. IT industry prefers engineers. Engineering syllabus is more inline with the current industry trends. Engineering syllabus covers the basics of software and applications. You also get hands on projects. In my view IT-CSE is better option.

Probably MCA. Because you're going to go absolutely nowhere with such a small degree under consideration.

Please specify a college or university for better assistance, it may vary from private to government college.
