Hindustan Institute of Technology and Science

Hello Tanmoy, Yes, a student of mechanical engineering at undergraduate level can surely think of doing PG in aeronautical engineering. Of course the student can not select "avionics" as specialisation. However, any sub-branch of aeronautical engineering related to mechanical engineering can be selected if the student selects appropriate paper of GATE.
Best wishes for your dream of pursuing PG in aeronautical engineering.

Hello Pavan,
Hindustan University has a reasonable reputation in academic circles. If you are getting admission, then there is no harm in confirming it.
Best wishes to you.

Hello Suhail,
These days almost all govt or govt owned organisations use GATE score for screening students whom they want to employ. Some court rulings also has made it impossible for such institutions to take part in placements process. However, you can apply directly based on advertisement on the website.
