Engineer

Hello Rushikesh, Actually speaking aeronautical engineering is the name of the course and aerospace is the name of industry operating in this field. Presently at least in India there is hardly any scope for employment in core areas. On the other hand, AME deals with servicing and main of civilian aircraft. In India passenger as well as cargo traffic is increasing by around 15% per year. This means more aeroplanes in Indian skies which in turn means more AME requirement. Tremendous opportunities for job.

Scope of engineering is directly proportional to the standard of the institute from where you will be doing your engineering. If you get into IITs, NITs or regional top institutes then your future is secure. But, doing engineering from random XYZ college won't ensure anything. In that scenario, one can pursue MS after the completion of Bachelor's degree.

Yes, it is sufficient but try to read all the chapters of text books with details.

It seems great that you are leaning towards Supply Chain Management, but both of these colleges will not help you in your future. I will suggest you to give CAT and go to some Top 20-40 college.

You need to give NCHMCT JEE for hotel management.

I would suggest you Lovely Professional University, because in this university they develops a student 3 dimensionally and not much eligibility is required.
