The Quizzes help pages are structured into three categories: Essentials, Advanced, and Troubleshooting (see topics listed under Quizzes on the menu to the left). Essential topics are the fundamentals that an instructor needs to know and use to build a basic quiz. Advanced topics go into more depth and detail. Advanced topics assume familiarity and understanding of the essential topics. Troubleshooting...well, that category speaks for itself.
