25-question, graded-as-you go, Cultural Literacy Tests on a number of topics: American and World History, Literature, Geography, Music, Science, Technology, Math.
So far I’ve just taken the two American history tests — I missed one (but got it on the second try).
Update: I aced the geography and did better than I expected on music.
That was kind of fun. There are many subjects to choose from, and it goes pretty quickly.
I took 5 tests (authors, quotes, mythology), and scored quite well on all of them.
