Guess we’re not overconfident nitwits. Tonight, anyhow.

Hey…I got 50,063 on that one, but I got them all right (one guess, but it was a correct guess). How did they know I guessed? How did you beat me?
By going to church during Easter - while I generally dislike going to church in English, that’s one of the periods where I’ll make the effort (me speakee modern English, not KJ). The cena part is just a linguistic curiosity: I knew both the English word, its Spanish version, and that the Spanish version has two other meanings which I personally have never encountered in English (a small tertulia or group of people who meet often to discuss their common interests, often over a meal; the room where such a group meets).
Is it difficult to believe that a Catholic might know a word that’s most often used during the holiest Catholic ceremonies?

Apparently I’m a bit of a dim bulb 
I got them all right too. My guess is that each word has an associated score based on how difficult it is. The test gives you a random assortment of words so each score is slightly different.
great username/snark combo.
too many checks, I thought it was going to estimate, not actually make me check off the words I know one-by-one 
Although in scanning the second page i realized I know a word I never knew I knew. Burgeon. I have only ever seen Burgeoning and never had any reason to consider that there was a base form of it. So whatever it was before, it is now +1.
That must be it, because I got them all correct, as well. Then it invited me to sign up or login through Facebook to boost my score some more. Since I’m now app-averse, I didn’t.
35,400 native English.
30,500, native speaker.
There were many words on the list that I have read, would understand in context, but didn’t feel comfortable saying I could provide a definition. I erred on the side of not checking rather than assuming I knew.
Probably because it was the only one on the first page I (and I would guess lots of us) didn’t know.
Oh, yeah, 35,200.
You were probably thinking of “oenophile.”

I’m with tdn - 28,700, native speaker.
39700 and native. Very few words I hadn’t seen, but quite a few I didn’t mark that I used to know…
Here’s one:

183 with a handful of outright guesses.
This pretty much. It told me 38,500 but there’s no way it could know that or even guess accurately based on self reporting. A number of the more obscure and out of date words I did not know through reading or use, but because they were typical vocabulary “test” words I had seen before in test taking prep materials. I would not vouch for the accuracy of this test.
And his friend Diana Wynne Jones wrote a story about a young dream worker whose name was O’Neir…
… does it count if you guess “it’s got to be this one which doesn’t make a lot of sense, because the other three no way”?
This has to be one of the hardest things to test for mechanically. If you make it multiple-choice, there’s the discard mechanism; if it’s free-form, then anything that’s not exactly what the machine had as acceptable is out, although it could be correct.
Yllaria’s link included a word I’d learned yesterday: troth 
Reading fantasy books pays.
