Germany

Hi Sam,
First and foremost, you have to complete your undergraduate degree from a recognised university. You must be academically very strong and sound to be considered for admission in a German university. Normally if we look around, students who apply or being accepted by German institutions are very strong academically and have percentages in the range of 85 to 90% and above. Some other key requirements also include knowledge of German language although many universities do not require prior knowledge of German language. You must also take the IELTS. Your profile must be competitive and consist of excellent projects, research etc. For the application process you can visit the university-ASSIST portal. You must also refer to the DAAD website for study related information in Germany. Always check university websites too for specific details.
Hope this helps.

The exact answer will depend on your desired programme of study and where you want to settle eventually. Both the country has its pros and cons. Even geographically both the nations are different. Germany is affordable compared to Canada. Germany is a well established study abroad destination and is very competitive. Students with academic and research oriented mindset apply to Germany and those with percentages as high as 90%. Canada is also a very big study abroad market now and has very good stay back options. In Canada you will find more degree options from diplomas to Masters compared to Germany. As I said the countries geographically differs you cannot compare the salaries, will depend on your qualification, job role etc. You must compare all these things and decide what is best for you.
