I live in Switzerland. I did GCSE German so had a basic understanding before I moved here. I now speak good German in my every day life, including with my work colleagues and DH’s family. I can express myself well and speak about a variety of topics. However, we live in a minority language area. That’s made it more difficult to learn German, because I hear the other language all the time (including at home).
I need to study for my job. I need C2 German, but they would accept C1. I’ve done an online Goethe placement test, which put me at B1. I understood almost everything on the test, but was let down by bad grammar (I don’t know if a word is der/die/das etc. Pretty basic stuff, I know).
So I need to get studying German properly, asap. Has anyone got any grammar book recommendations? Or other tips? And does this even sound doable? I have 3 years to do this. C2 level feels very out of reach.
