Can you give more background on this Vocabulary Size Test?

We first launched the quiz in May 2016. It was created by a group of native English speakers, including some IELTS teachers. We utilized various online sources for English vocabulary distribution to design the algorithm.

When our friends shared the test on Facebook and Twitter in Jun 2016, it became very popular a few weeks later. In 2017, we posted an answer to the test on Facebook, and it went viral again in 2020.

It's been years since we launched the vocabulary size test, and we continue to update it periodically. If you have any suggestions, please feel free to leave a comment after taking the test.
