Frequently Asked Questions

The common notion is that foreign universities are expensive, although with scholarships this is an exaggerated issue. What many fail to consider are time and effort. Studying in an Indian college leads to a lower average salary than earned by our western counterparts. This salary sets the tone for all future promotions since companies often look at your previous salaries during compensation appraisals. Additionally, most senior positions tend to be scooped up by individuals who have an international outlook through global exposure.  Finally, studying in a foreign country is an incredible learning experience helping students get a better academic as well as soft skill development.

Canada has been one of the market leaders in education for decades. However, what currently sets Maple Country apart is immigration. Canada is wholeheartedly inviting students to study in their universities to fill job vacancies that are always growing in the country. Students who study in Canada (especially a Master’s Degree) are practically assured of a Permanent Residency Visa.

A good score doesn’t automatically qualify a candidate for a scholarship, however, it is one of the primary factors that the admissions department looks for in a scholarship application. There are other attributes such as a candidate’s academics, extra-curricular, financial background, and application essays (SOPs).

We get this question a lot. Many candidates know which career path they want to take, but are at a loss for how to take that journey. Understanding the job role and the industry that you want to get into is the first step to picking the right university.

Carefully consider the immigration options of the country that the university that you are considering is in. This is more important when you intend to stay back in the country after the completion of your course.

Also, review the placement history of the university as well.

The first step is to list your preferences. By listing your preferences and strengths, describe your course of preference. Extensive research on the modules, software and its length for your preferred subject is necessary.
