I was actually a bit surprised, not by the specific number of words (that seems reasonably fair given some statistics posted above on this thread), but on the percentage ranking. I'm a doctoral student whose vocabulary score was in the 96th percentile on the GRE and I knew every word when I took the WAIS-IV. Here, my score of 28,300 is just a bit above average. Either people are lying (possible) or this curve is clearly not a normal curve representative of the population (most likely). I'm a pretty avid reader, even though most of the older authors like Dickens bore me (thanks ADD!), but the person that came up with those words is possibly the most voracious reader I have ever met.

I also just realized that taking the test primed me to write in a way more intelligently sounding manner than I usually do. Not an LOL in sight!
