Hi softsafari,

I believe you are referring to the “area” parameter. This parameter allows you to specify a test (es, ms, hs, ksat, toeic, toefl, teps, sat, ielts, gre, gmat, overall) for your quiz. The quiz generated will focus on words often found on that specific test. Specifying “overall” will pull words regardless of tests.

Thanks!
