The Norton Anthology of English Literature Quiz (via Bookish)
I scored a miserable 7/10 on the 10 question version of the 20th century literature quiz. I could have reasonably gotten 8, but I forgot the publication date of The Way of All Flesh. The other two I got wrong were, I think, pretty obscure, and I forgive myself.
These might be useful quizzes to try if you're thinking of doing graduate work in English literature, and need to take the GRE English subject test. And for my English prof. colleagues out there, it might just be fun to take it.
