Powered by Cerego, Mastery Training activities adapt to each student's performance to help them learn and apply concepts efficiently and effectively. Relying on the principle of distributed practice, these assignments require each student to follow a schedule and review core concepts in small chunks over time. Mastery Training refreshes your memory for each item just as it's about to fade by tracking your performance, measuring pace, response time, and accuracy to predict the best time to review. The result is a personalized experience that leads to long-term retention — and a learning engine that gets more effective the more you use it.
