This is a quiz report plugin that allows the teacher to quickly check the time elapsed since the last interaction of each student with the Moodle server during a quiz attempt.

Recent interactions are a good sign that the connection is fine and the student is able to work normally. If there have been no updates for a while, this can indicate problems with the connection or the student's device. If a large group of students have not had interactions for a longer time, there might be a problem with the network infrastructure in the exam room.
