German relative clauses: der, die, das that actually bind
How German relative clauses work in real sentences: the relative pronoun, the comma, the verb at the end — and the mistakes that cost B1/B2 points.

The job of the clause
A relative clause points back at a noun and tells you which one, or adds a fact you needed. Das ist die Frau, die gestern angerufen hat. The comma is not decoration. The conjugated verb waits at the end of that clause, the same way it does after weil.
English can drop the pronoun (the woman I met). German cannot: you need die / der / das / den / dem / denen matching the noun's gender and the case *inside the relative clause*, not the case of the noun in the main clause.
Case is decided in the relative clause
Die Frau, die ich gesehen habe — die is accusative because sehen takes an object. Die Frau, der ich das Buch gegeben habe — der is dative because geben gives to someone. The woman is the same person; the pronoun still changes. That is the whole trick.
Plural die in nominative and accusative, denen in dative: die Leute, denen ich geholfen habe. Genitive deren / dessen exists in writing. In speech you will hear people avoid it. In Goethe Schreiben, using it once correctly looks like control, not showing off.
Prepositions ride with the pronoun
in dem can contract: im is for the preposition in, not a special relative. Das Büro, in dem sie arbeitet. Die Frage, mit der ich nicht gerechnet habe. Keep the preposition that the verb wants. Inventing wo for every place is how A2 habits leak into B2: wo is fine for true places (die Stadt, wo … is debated; in der is safer in an exam).
What to practise
Take five nouns you actually use — Prüfung, Kollege, E-Mail, Problem, Lösung — and write one nominative and one dative relative each. Then meet them as blanks. If the option set is die / der / den, you are practising the real exam move, not a crossword.
