Yes, you can apply. If you meet the admission requirements such as percentage, IELTS or TOEFL scores etc. and the university likes your overall profile you will be admitted.

Hi, please be more specific with the country of your choice.

Opting mechanical would be a better choice. You will be eligible for more inter-disciplinary fields like civil, electrical, electronics, chemical, agriculture, metallurgy, automobile, etc. posts in both, government and private sectors.

Yes, of course. There is no limit to learning. It will add a good advantage to your resume.

Hi,
According to your given profile you can surely apply to Canadian Universities to pursue your Masters.

Dear Adil,
I do not know anything about Poland as I do not deal with this country. Australia is a good place as far as lifestyle, quality of education and employment for mechanical engineers at present. The other choice if you have scores above 75% is Germany as the cost will be very low or even free if you get a scholarship.
All the best!

Hi, your grades are too low for both the countries. You may still find very little options in Canada but Germany is a tough call. You can look for suitable options in Australia or even New Zealand. These countries too have a great demand for graduate mechanical engineers.

Yes, it's possible. There are very few colleges in India, which offers Masters in aeronautical engineering. You will need to take GATE and also research about other requirements for getting admission into ME or M.Tech courses offered at these colleges. IIT - Bombay is one such college.
