Repetitions
A learning repetition occurs the very first time you study a variation. The default is set to 1 repetition, but you can choose up to 3. The maximum is limited to 3 because we simply do not think it is productive to do more than that when learning material for the first time.
How do I change the number of repetitions in my course?
You can adjust the number of repetitions for your course, from 1 to 3, by using the 'Repetitions' drop-down in your course settings.
