Hi there, question is what did you use to learn so far? Is it only your vocabulary you are bothered about? How do you like to learn, what is your learning style? This is how I got on the road with Danish but it's got a grammer that is a lot simpler than German. I took classes, A1 over A1 because I could not take part in a class continuously. I was really annoyed. At some point I decided on self studies and read my first book, online articles would be good too. At first it was no reading, it was more or less just looking up words for me, making flashcards, learning. At some point I was up to 1500 new words besides the basics I already knew. In Danish ( as I said simple language because similar language, easy grammar) this was enough to read read read. Now my reading is as fast as in German and in English. my passive vocabulary is good enough. Now I am at the point that I need to listen and talk. Talking is difficult so writing must be it. Listening I have to force myself , cuz I think it is boring...I met people who use music to improve their skills, some use dubbed films, audiobooks, online radio stations, there are slowly spoken news available. So it depends on your time and preferences? This would be good to put into discussions btw. You will get more input I think.
