What it does
Take a short, scientifically-grounded test and discover your real English vocabulary size — and the CEFR level it corresponds to. Then keep growing: words you miss go into a personal review deck and come back at the right time with spaced repetition. Useful before exams, job interviews, language courses, or just to track your own progress over time.
