Questions in Quizzes and the Question Library

Any question that appears in a quiz (including those in random sections) exist within that quiz, so anything that is in the Question Library is extra. The Question Library is useful if you want to reuse questions in multiple places (say in a chapter quiz and again on the midterm or final), but once questions appear in a quiz their existence in the Question Library is unnecessary. This is not the same as in Blackboard, where pools have to exist if the instructor is using random blocks. In Desire2Learn, every time a random section is created in a quiz, the possible questions are copied into that quiz.
