Argumentative writing at B2 is not simply expressing an opinion; it is building a position supported by clear logic that a German reader can follow step by step without ambiguity. This is exactly what the Goethe-Zertifikat B2 measures in the Schreiben section when it asks for a roughly 150-word Kommentar: having an opinion is not enough — you must organize it into the strict structure a German reader expects.
The standard structure has five steps: an introduction (Einleitung) presenting the topic neutrally, a thesis (These) stating your main position clearly, arguments (Argumente) supporting that position with concrete examples rather than bare assertions, a counter-argument (Gegenargument) that acknowledges an opposing view before refuting it, and finally a conclusion (Schluss) that summarizes and opens toward a wider thought. This linear order reflects a preference, strong in German academic and professional writing, for clarity and a direct line from idea to conclusion; rhetorical habits that favor restating an idea in varied phrasing or building persuasion through digression can, in German, read as disorganized even when the underlying content is sound.
The most important linguistic tool here is Konnektoren, connectors that signal in advance what role each sentence plays: Erstens/zweitens for sequencing, Außerdem/Darüber hinaus to add an argument, Allerdings/Dennoch to introduce a reservation or counter-argument, Daher/Folglich for a logical consequence, Zusammenfassend for the conclusion. Each connector tells the reader in advance what kind of logical relationship is coming, making the sentence predictable and easy to follow.
The most frequent mistake at B2 is confusing "Meiner Meinung nach," which introduces a general personal opinion, with "Ich bin der Meinung, dass," which requires a full subordinate clause with the verb pushed to the end (Verbendstellung). Many learners write "Ich bin der Meinung, dass ist es wichtig," carrying over main-clause word order, when the correct form pushes ist to the end of the subordinate clause: dass es wichtig ist.
