When a student is in the question queue, a number appears before the student's name under the 'Question Queue Column' in the Instructor Roster as shown in Figure 2.6.2.2a . The number shows the instructor the order of the student questions. Students in the question queue will be sorted by their queue number and listed at the top of the student list. The rest of the class who are not in the question queue are sorted by alphabetical order of their names and listed after the question queue list. The number '1' means the student is the first to enter the question queue.

When a student is removed from the question queue, his name will be listed under the question queue and sorted in alphabetical order.
