The Adaptive Quiz plugin is a new activity module that allows instructors to administer an adaptive style quiz. As the student attempts the quiz an algorithm uses a formula to choose questions and estimate the students ability within a certain amount of error. When adding/editing the adaptive quiz, instructors can define the activity parameters that will be used by the algorithm while the student is attempting the activity. The adaptive quiz requires the use of both question bank categories and tags, in order to determine the questions that will be displayed during an individual user's attempt. Tags are used to assign the questions difficulty levels. Then categories of questions can be assigned to the adaptive quiz question pool.
