Thank you, Sung Kang! You posted this with the absolute best timing ever! Now I don't have to go over a dictionary to improve my English vocabulary for the IELTS.

Guys, please try out FreeRice.com.

The site sponsors donate 20 grains of rice for every correct answer to English vocabulary multiple choice questions to Third World countries. So not only do you improve your vocabulary, you also get to do charity work at the same time. Neat, ne?
