Random question type
Note: You are currently viewing documentation for Moodle 2.2. Up-to-date documentation for the latest stable version is available here: Random question type.
A random question is not a question type as such, but is a way of inserting a randomly-chosen question from a specified category into a quiz.
This means that different students are likely to get a different selection of questions, and when a quiz allows multiple attempts then each attempt is likely to contain a new selection of questions.
