German C1 exam grammar: core review checklist
This is a focused review of core grammar topics, not an official syllabus or a complete exam simulation. Exam providers also assess reading, listening, writing and speaking; use their current sample papers alongside this practice.
Reviewed against official exam-provider information on July 30, 2026.
Goethe-Zertifikat C1, telc Deutsch C1 Hochschule and TestDaF are common advanced-German routes, although recognition requirements depend on the institution. This page reviews four areas that support formal written German: demanding case structures, adjective declension, formal prepositions, and verb-to-noun transformations. Use it alongside official sample tasks for the complete exam format.
Where grammar appears at C1
telc C1 Hochschule includes language-elements work based on academic prose. In Goethe-Zertifikat C1 and TestDaF, grammar supports accurate reading and productive performance within broader language tasks. Official sample papers remain the best source for current task types and scoring criteria.
The practical challenge at C1 is using familiar structures accurately in dense, formal contexts and under time pressure. Timed drilling can help with that fluency, but it covers only one part of exam readiness.
The C1 core grammar checklist
These are the four core topics in KasusKnacker's focused C1 review track. Each links to a grammar guide with tables and examples.

Read the Formal-register prepositions guideSubjunctive, passive and nominalization
Read the Subjunctive, passive and nominalization guideCases in demanding contexts. The four cases inside extended participial attributes („die von der Regierung angekündigten, seit Monaten erwarteten Reformen"), chained genitives, and appositions. The rules are old; the parsing load is the C1 part.
Adjective declension at C1 level. Endings within nominalized adjectives („das Entscheidende", „alles Gute"), after indefinite quantifiers („vieler kleiner Betriebe"), and in the extended attributes above — where one wrong ending breaks a whole construction.
Formal-register prepositions. angesichts, infolge, mangels, gemäß, zufolge, seitens — the prepositional inventory of official and academic German, mostly genitive-governing, each with its own quirks (zufolge takes the dative and follows its noun). These are high-frequency items in every C1 reading text.
Subjunctive, passive and nominalization. Konjunktiv I for reported speech („Die Lage sei stabil"), passive in all tenses including with modals („Die Frist hätte verlängert werden müssen"), and the systematic verb-to-noun transformations of Nominalstil. Together they define the register C1 writing is scored on.
The four exercise formats, with examples
KasusKnacker's C1 track uses four exercise formats modeled on how exams present grammar. Here is each one, with a real C1-level example — try it before revealing the answer.
Gap texts (cloze)
Formal texts with gaps — the format used in the telc language-elements section.
Example
Angesichts ___ zunehmenden Kritik sah sich der Vorstand ___ Herausforderung gegenüber, das Vertrauen ___ Öffentlichkeit zurückzugewinnen.
Show answer
der (angesichts + genitive) · der (gegenüber + dative) · der (genitive attribute) — three identical articles, three different case assignments.
Word-bank texts
Fill the gaps from a shared word bank — the second telc grammar format.
Example
Word bank: zufolge · mangels · gemäß
Dem Bericht ___ steigen die Kosten weiter. ___ eindeutiger Beweise wurde das Verfahren eingestellt. Die Anlage wurde ___ den geltenden Vorschriften errichtet.
Show answer
zufolge (postposition + dative) · Mangels (+ genitive) · gemäß (+ dative)
Spot the error
One part of each sentence is wrong — find it and correct it.
Example
Die Entscheidung, die gestern getroffen worden war, wurde heute widergerufen.
Show answer
The error is widergerufen — the verb is widerrufen, an inseparable verb whose participle takes no -ge-: widerrufen.
Transformations
Rewrite a sentence in a new form — here, from clause to nominalization.
Example
Nachdem der Vertrag unterzeichnet worden war, begannen die Bauarbeiten. → Nach der ___ des Vertrags begannen die Bauarbeiten.
Show answer
Unterzeichnung — the temporal clause collapses into nach + nominalization + genitive attribute.
Coming from B2
C1 builds on the B2 exam grammar page — active genitive, fixed-preposition verbs and basic Nominalstil. If any of it feels uncertain, review those foundations before tackling the same structures at greater density.
