This quick test (about 2 minutes) accurately assesses how much English vocabulary you know.
Ive taken it 3 times, and I got 73%, 79% and 83%. My advice is to go as fast as possible. That was how I got my score higher each time. I never flagged any non-words as actual words. I was quite happy with that given how quickly I was going.
Who can get the best score? You must supply proof in order to win. I will upload screenshots but I’m sure someone will beat my best after a few goes so not worth it currently. Highest proven score becomes official ROF vocabulary champion.
