Reason being if 你 know all of the allocated words it doesn't mean 你 have a large vocabulary 你 could just know those words. I use to read the dictionary for fun when I was younger so I know words like infinitesimal and hundred dollar words like that come easy to me. I guarantee 你 if alot of the words that I remember when I was younger was on the test. It'd be like over a 35k to 40k guesstimation
I wouldn't put an insane amount of stock into the nature of the test. Considering depending on what words 你 get in the test it can be bias.
Guessing my vocab. It's prob around 30 to 40k. Somewhere in that vicinity. It could be lower 或者 upper 30k but it's somewhere there in that vicinity.
