Think I have the lowest score here. 16,400 words. English is not my native language but I speak English daily and I wouldn't say my English is bad. Pretty disappointed with the score and also surprised the median is way way higher than I expected.

Edit: And, also to add, I followed 2 criteria for whether I know the word or not.

1. What's the absolute definition?

2. And can I find the equivalent or meaning of it in my native language? (which is Tamil, an Indian language, if anyone cares.)
