German C1: Advanced

4,426 C1 words, commonest first, each with its meaning, its forms and a real example sentence. 50 short reading texts, easiest first, with an English translation for every line: in the first one you already know almost every word. 4,147 conjugation and declension tables for the C1 words, and 214 mistakes real learners made at this level. 675 practice questions, every answer explained.

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.

C1 itself adds 4,426 words to what you already have; cumulatively from A1 that is about 9,570. Syllabuses vary by a few hundred either way, but the order matters more than the total: the commonest words carry most of the meaning.

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.

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.
