I don't think it's necessary to learn something practical. It doesn't really matter if you don't take the exam. German is more difficult. If you don't have a little foundation, it's really challenging to take CET-4. I've studied German for two years, and it's only a rudimentary level. If you want to research, let's go to Calder Ford. At least it is useful for finding a job and studying in Germany.

I suggest you go to the Training College of Foreign Studies University. There is a learning atmosphere and the teaching quality is guaranteed.

As for the specific foreign language schools, I suggest you consider beijing language and culture university and Xi International Studies University. German in these two schools belongs to the national key majors.

Of course, Beijing Foreign Language, Guangdong Foreign Language and Shanghai Foreign Language are also good.
