Students may wish to re-visit some of their previously completed topics and take lessons, whether it be for revision, or if they've completed topics where lesson interventions have been disabled. Either way, they can easily do this!
To re-take a lesson:
Have your students log into their account.
Go to the 'Activity' page.
Click 'Results' on the topic they'd like to review.
Choose the question they'd like to work on and click 'Take Lesson'.
Lessons are available for each question within a topic and there's no limit on how many lessons can be taken π
