Those are usually questions to assess your understanding of what you will be studying and to guarantee that you will succeed.
The scope of studies might mean:
- What kind of studies do you want to carry?
- How much time will it take?
- Why choose this country in particular?
- What do you want to do after graduating? (to check if your career goals match)
You can also expect questions:
- Regarding your previous studies (to see if it matches more or less your orientation).
- Regarding your awareness with what it takes financially, or if you master the language of the country you are going to.
Hope this helps!
