Wortschatz.tk

A German vocabulary test inspired by testyourvocab.com. Unfortuntely I lost the domain name for my own test, and TestYourVocab appears to have been swallowed by a marketplace for language tutors.

I basically just wanted to find out about my own vocabulary, but eventually went down the rabbit hole and dug deeper into vocabulary stuff than any sane person would ever want to. Your German vocabulary on a curve is the text where I analyze the results that were collected over the 2+ years while the test was online.
