How many correct answers are needed to learn a topic?

Student progress within a topic is based on a point system. Students are awarded one point for a correct answer, and two points for two correct answers in a row without using the Explanation page. One point is subtracted for an incorrect answer. The number of points will not go below zero. A real-time progress indicator displays students’ progress in the current topic. Once five points are earned within the topic, the progress indicator will be entirely filled in and the topic will be learned.
