Mastery levels and how they are calculated

• Not started — You have not encountered this topic yet. It is waiting in your learning plan for the tutor to introduce.
• Learning — The tutor has introduced this topic and you are building understanding. It will come back for review soon as you work toward a solid grasp.
• Practiced — You have a solid understanding of this topic. Reviews are spaced out at increasing intervals, giving you time between sessions while keeping the knowledge fresh.
• Mastered — You have demonstrated strong retention across multiple reviews over an extended period. The topic still comes back occasionally, but only rarely.

Mastery is not based on a single test. Epivo evaluates your understanding through natural conversation:

• Can you explain the concept in your own words?
• Can you answer questions about it correctly?
• Can you apply it to related scenarios?

The tutor assesses these things during every interaction. There are no separate quizzes or exams.

Yes. If you struggle with a topic during a review, the scheduling algorithm reduces the interval and brings it back sooner. This is completely normal — it means the system is working to strengthen your understanding.

True mastery builds over time through repeated, successful recall at increasing intervals.
