If a student does not pass a skill based on the passing percentage, Moby will automatically give the student another variation of the same skill. However, if the student fails two to four of the variations in a row (the number varies based on the skill), Moby will post the score for that skill, and it is up to the teacher to decide whether or not to reassign it.

Moby will not reassign an entire lesson, but the teacher can always reassign an entire lesson or an individual skill in their teacher account.
