I was reading the book How I Learn Languages by Dr. Kató Lomb, a great Hungarian polyglot who knew 16 languages, where she offered a very quick way to test your knowledge of the language by testing your vocabulary. I had some hours yesterday so I adapted her way and made it into an online test where you can test your knowledge of French, German, Spanish or Lithuanian in a minute or two. The test gives you an answer in the Common European Framework of Reference for Languages.
