Allowing the Students to Re-take the Lesson

This setting determines whether the students can take the lesson more than once or only once. The teacher may decide that the lesson contains material which the students ought to know throughly. In which case repeated viewings of the lesson should be allowed. If, however, the material is used more like an exam then the students should not be allowed to re-take the lesson.

When the students are allowed to re-take the lesson, the grades shown in the Grades page are either their average grade over the re-takes or their best grade for the lesson. The next parameter determines which of these two grading alternatives is used.

Note that the Question Analysis always uses the answers from the first tries of the lesson, subsequent re-takes by students are ignored.

By default this option is Yes, meaning that students are allowed to re-take the lesson. It is expected that only in exceptional circumstances will this option be set to No.
