When I was planing to come to Germany one of the things that I think the most was finding a good school , and selecting one is not very easy while there are plenty of advertisements and brochures that maybe you will find interesting but you are not really sure if is the correct one that will cover your expectations, also depends what are your goals or priorities.
I started my research and saw the choices that I had, for me was very important to find a school that offers fewer students in a class so would be easier to learn as the teacher is more focus in the students.
Also I was looking for one school that would be able to give me the resources to learn German fast, and provide good teaching quality.
The teaching quality is very important and could be the 50% that you need to learn a foreign language and the other 50% its up to your motivation, practice and goals.
So far I can say that the DeutschAkademie offered what I was looking for!!!
