The expense is in the technicality of getting the right questions that assess each one of those levels. We use them at such high volumes. Close to 70,000 of these we do in one year, the reading and the writing—and in both languages. It has to be done in English and in French, and there's a comparable level of complexity. I make sure that when you pass, when you do a test with 80 questions, we get it right as to whether you're level A, B, or C.
