B2 is where comprehension becomes fluid. At this Goethe-Institut level, you can understand the main ideas of complex texts on both concrete and abstract topics, interact with native speakers with sufficient fluency, and produce clear, detailed text on a wide range of subjects.
Focus on nuance — synonyms with different registers (umgangssprachlich vs. formal), collocations, and idiomatic expressions. Many B2 words appear in academic and professional contexts, so pay attention to the example sentences for register cues.
Extended adjective constructions (Partizipialattribute), nominal style, advanced connectors (dennoch, infolgedessen), genitive case in practice, complex subordinate clause chains.
