Learning checks are short quizzes that consist of 6-12 questions derived from the course material. Questions do not have a time limit and you can review the related clip to the question if you gave an incorrect answer.
Learning checks are meant as self-assessment for you to gauge if you have a good grasp on the material within the course. You can take learning checks at any time and as many times as you would like. Learning checks are not visible to anyone even if you are in a group plan.
