How would you setup your WBS?

Assume you were appointed as project manager to lead a dozen of your classmates to write up an end-of-course summary guide that would be used to update all areas of the course (i.e. discussion questions, lectures, assignments, quizzes, and exams). You plan to form sub-teams to work each of these elements, each headed by a sub-team leader. How would you setup your WBS? What are some considerations you made when you decided on this structure?
