Fluent Englisch teacher with C1 CEFR level (IELTS)

I am a master student studying Astrophysics at LMU München. After coming to Germany, I felt that there is a much required need to learn German language as well as if more people could understand English, that would be super. I have studied in an english speaking schools and universities until now, so I'm quite fluent in speaking in English. I also have a C1 level of CEFR in IELTS.
