The student’s usage-counter is used to keep track of their weekly usage. The total number of minutes that the student has spent learning is shown at the top of the bar, and the usage counter is reset on Sunday midnight (local time). A student receives credits by using tutor, replaying exercises and creating challenges in topic challenge. The counter shows the amount of credits a student has earned that week, and in total. Students can earn up to 15 credits for a tutor exercise, 30 credits for a test and 10 credits for a replay exercise.
