     How does the FreeRice vocabulary program work?

     FreeRice has a database containing thousands of words at different levels of difficulty. There are

words proper for people just learning English and words that will challenge the most learned professors.

     In between are thousands of words for students, business people, doctors, truck drivers…

everyone!

      FreeRice adjusts to your level of vocabulary. It starts by giving you words at different levels of difficulty and then, based on how you do, designs a proper starting level for you. When you get a word wrong,

you go to an easier level. When you get three words in a row right, you go to a harder level. There are 60

levels in all, but it is rare for people to get above Level 50.
