Hello, my name is Nour, I am 18 years old. I am Tunisian. I live in Tunisia. I will pass the baccalaureate debate next June, but I started looking for the best university to study accounting and business administration.
I speak good French, English and a little German. I have reached A1 level in Germany

Wondering why this post is not just on the thread to introduce ones self instead of under a new heading "cost of living" which it has nothing to do with.

But a simple answer is that while many masters programs are offered in English, the vast majority of bachelors are in German on a C1 level. Reaching this level from A1 is a good 18+ month full time effort in a language school. Likely a much better chance studying in an English or French speaking country.
