I hereby advise all those who study in Germany not to go through intermediaries. The process of studying in Germany is very transparent, and there are few intermediaries now. After graduating from undergraduate course, apply for APS first, then apply for a visa to study abroad, and then go to Germany for language classes according to your own situation. If you are good at German, you can take the DSH daf exam directly and enter the university. Don't think that it is generally impossible to apply for international courses (that is, English teaching). All the people I know who take international courses are Australian and Canadian students, and their mother tongue is English. In addition, the project has a history of more than 3 years ... I personally think it is very unreliable.
