Clinical Cases and Quizzes are self-assessment tools that you can use to test your knowledge on the Concepts you studied. Both contain questions that have 2 levels of question feedback: (1) feedback for the answer choices and (2) a list of objectives that the question is focused on. Clinical Cases are slightly different from Quizzes. Quizzes are structured to test your knowledge of the Concepts. They tend to be more focused on a lesson or topic. Clinical Cases broaden this focus to cover even a number of Areas. As you go through a case, you will most likely be using your knowledge to answer a question that spans a number of Topics and even Areas.
