CBSE 12th

First complete your graduation.

No, science background is not necessary for this course. You can be from any stream to pursue the media course.

Shanti Business School, Oakbrook Business School, L. J. institute, Nirma University, Ganpat university, St. Kabir Institute &BK School of Business Management these all colleges provides MBA in IB.

You can go for any computer career options but you also need to take Maths as a subject for entrance exam.

This is the same question that I too have, according me you do your (UG) in Mechanical engineering (B.Tech) in one of the best colleges in and around India and then, after your degree in (B.Tech), do your (PG) in Robotics and Automation (M.Tech) in India or try to do it abroad countries, and doing Ph.D in Robotics isn't worthy enough and it has no value, if you want to pursue your career in teaching the youu could do your Ph.D in Robotics, otherwise, it's not needed.

There's a very slight possibility of you getting converted to wellingkar, if you perform exceptionally well in GD and PI. Prepare accordingly. All the Best. Thank you.

It depends upon on the college you select. It should be conducted by NCHMCT, and by else.
Thank you.
