The Librarian You scored 65 erudition!

Congratulations! You're well above average when it comes to your knowledge of English grammar, history, and literature. You may have missed a few questions, but if you keep your studies up and stay away from genre fiction, we'll have you ready for Stanford in no time! Who knows, we just might be reading your columns in Talk of the Town a few years from now.

My test tracked 1 variable How you compared to other people your age and gender: You scored higher than 9% on erudition
