Test Your Vocab: How Many Words Do You Know? The webiste which I am ıntroducing you helps you estimate how many English words you know approximately. You check the words that you know (meanings of the word), and then you give more information about you such as birth year, country, etc. The website will try to estimate your vocab!
"TestYourVocab.com is part of an independent American-Brazilian research project to measure vocabulary sizes according to age and education, and particularly to compare native learning rates with foreign language classroom learning rates.
It functions by means of a quick three-part test: the first part with a handful of words to determine the general vocabulary level, a second part with a larger but narrower selection of words to determine the vocabulary level with greater precision, and a final (optional) survey to collect statistical information.
The site provides accurate results for virtually everyone, from very small children (with answers input by parents) to professional linguists. It can calculate vocabulary sizes from less than 100 words to more than 40,000 words." (retrieved from http://testyourvocab.com/about)
