German, math, math basically don't need to read, only fools will, take a good look at German, they are all endings and the like. I took the exam many years ago, but I don't remember it now. There are sample papers on the websites of general exams, and when you apply for a university, the university sometimes gives you sample papers, and if you don't give them, ask them for them. After graduation, it is not a problem to enter these three schools. It's much easier for preparatory students to enter the school than to apply directly ~ I heard that only TUM rejected preparatory students, and other schools have never heard of it ~ ~

To answer your later question, you don't want Telford's matriculation grades, as long as you have 600 hours of proof. The preparatory course is a written test, and the test results don't matter. It doesn't affect your application for the preparatory course. As long as you go to the preparatory course, it is no problem to apply for graduation in these universities, and you will basically not be rejected. And the level of German schools is similar. You only choose famous universities in China. They are already universities in the setting sun, and their strength is ok, but they are definitely not top-notch. The top universities are Munich University, Munich Industry, Karlsruhe Industry and Aachen Industry.
