BCA

Hi Parth,
Many universities in the US do accept three-year degree. You have to get a WES evaluation of your Bachelor's degree for this. Please check the websites and email them. Universities which strictly mention they don't accept three year degree won't oblige and no point negotiating with them. Take your GRE too.
Good luck.

BCA is not tough. Any average student can easily undertake this course. You are required to be attentive in the class and work hard to clear all the subjects with flying colors.

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.
