Vocabulary placement test

Answer 18 adaptive word-meaning questions. Correct answers increase the difficulty; incorrect answers lower it. The highest band, C2 / Above C1, uses about 75% source-verified C2 words and 25% C1 calibration words. Unclassified words are excluded from questions and answer options.

Difficulty sources: American Oxford 3000/5000 and Octanove C1/C2. The result measures word-meaning recognition only; it is not an official CEFR certificate.
