Because my students read this novel almost completely out of class, my quizzes are simple reading check quizzes. My objective is to make sure they are keeping up, and if they're not, to get them back on track. I teach 3 sections, so most of the time, I give these quizzes orally and choose five questions at random. I use different questions for every class to cut back on cheating.
The highlighted questions cover material that appears on Spark Notes.
