One of the ways to monitor user progress is through knowledge checks such as quizzes. Not only do Quiz Results show which users are excelling, but results are the first step in understanding how to improve lessons and courses over time.
Go to Analytics > Click Quiz Results
The results for each of the quizzes taken will be shown in the table. Items in the table can be filtered and searched for simple and quick access. The filter fields include "User," "Quiz," "Lesson," "Course," "Score," and "Date."
