The best way to see the progress of your learners is to test them throughout their learning journey. Simply add a few quizzes throughout your course to ensure the information is being consumed.
A quiz in a course will help your learners focus on the information that is critical as well provide great feedback to the course author. All quizzes can be tracked and easily linked back to the course and success of the learners. This will allow the author to understand the areas where the learners are struggling and make changes or updates to the course material.
