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

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.
