Efficiency is calculated by taking into account both the accuracy and speed of a student's work in MobyMax. When a student answers a question correctly, their efficiency percentage will increase. However, if they answer a question incorrectly, their efficiency for that question will be 0%. The faster a student answers questions correctly, the higher their efficiency percentage will be overall. This metric is useful for tracking not only how much work a student is doing in MobyMax, but also how well they are comprehending the material. 

Teachers using the new version of MobyMax will see the Efficiency metric in real-time through Live Real Time, allowing them to monitor student sessions as they are actively signed in. In addition, this metric will also appear on various Custom Reports and progress monitoring reports, providing a comprehensive view of student performance and progress over time.
