I entered incorrect values many times in the demo and it just proceeded with the pre-programmed lesson. The lesson seems quite linear, with no substantial opportunity to return to reteach principles that are greatly misunderstood. A real tutor would actively assess the points of misunderstanding and develop new strategies for helping the learner understand. This tutor mostly seems interested in moving the learner to the next step of the lesson.
