I also tried the test... And that's the result.
Advanced
You scored 100% Beginner, 92% Intermediate, 86% Advanced, and 73% Expert!
You have an extremely good understanding of beginner, intermediate, and advanced level commonly confused English words, getting at least 75% of each of these three levels' questions correct. This is an exceptional score. Remember, these are commonly confused English words, which means most people don't use them properly. You got an extremely respectable score. Thank you so much for taking my test. I hope you enjoyed it!
Edit: Tried again. The result is the same, but the numbers changed
I won on the Intermediate level, but lost on the Expert level.
