Welcome to all German self-learners!
Why is it worth learning German?
Many international students come to Germany to benefit from the quality of university teaching. Germany has overtaken France as the most attractive non-English-speaking host country for foreign students. This was shown by the report "Wissenschaft weltoffen 2019" by the German Academic Exchange Service (DAAD) and the German Centre for Higher Education and Science Studies (DZHW).
However, speaking and writing German at the university level requires a lot of motivation, time and money. In order to be admitted to a college or university, to find a job or to immigrate to Germany, good knowledge of German language and culture is required. And this usually has to be proven with a language test.
The best solution is to take a DaF language course (Deutsch als Fremdsprache) and regularly practice German pronunciation and grammar. To build on your previous knowledge, you will find many self-learning aids that you can use in addition to language courses.
