Language learning in German

 i'm learning German and I'm intermediate and taking a B1 exam in Freiburg in Germany. While I am learning it I've also looked at how we learn it. You have to do the structured parts - vocab + grammar and free reading and speaking to increase your understanding. I've looked at beginners books in technology such as AI and the poetry and prose of Bertold Brecht. The goal is to pass the exam but have a broader view of German culture and identify the key to the language that will be a catalyst for further learning.
