Interesting way to improve your vocabulary while at the same time making the world a better place. Food for thought, so to speak. Thanks for the tip Ursula!
I was starting to get a little frustrated because since I kept getting them right, ie guessing the correct meaning of some really hard words, I kept getting EVEN HARDER words! I somehow got the first 19 right before I guessed wrong on "eguitation". Later I found out there are 50 levels. I would advise students to get a few wrong "on purpose"?? so they stay at a non-frustrating level.
Besides, what good is a big vocabulary anyway...?
