The course element self-test allows the learners to perform an unlimited number of knowledge tests. The results are only visible for the learner. The author does not receive any information on whether or not or how often the self-test has been carried out.
All information for learners and authors can be found in the Help pages of the course element test.
If the course progress indicator is activated for a course, the course element will be automatically marked as completed upon the first finished attempt of the user. This process is independent of any possible assessment.
