Common questions
What is German C1?
C1 is the advanced level of the CEFR, formally "Effective Operational Proficiency". Express ideas fluently and use German flexibly for social, academic and professional purposes.
How many words do you need for C1 German?
C1 itself adds 4,465 words to what you already have; cumulatively from A1 that is about 9,522. Syllabuses vary by a few hundred either way, but the order matters more than the total: the commonest words carry most of the meaning.
How long does C1 German take?
The Goethe-Institut's own rule of thumb is roughly 800–1000 hours of guided study to reach C1 from zero, assuming you also work outside class. Someone who already speaks another Germanic language will be at the low end.
Which exam matches C1?
Goethe-Zertifikat C1 and telc Deutsch C1 both map directly onto this level. TestDaF and DSH sit around B2–C1 and are the usual route for university admission.
