The purpose of Knowledge Center personalized content is to allow you to complete an objective assessment of your skills in the subject matter and then take a subject that contains only the content upon which you need to focus. When an author or subject matter expert creates an assessment, he or she includes questions associated with subject content. When you complete an assessment, the Summary page displays a list of sections upon which assessment questions were based and includes your score on the questions for each section. Knowledge Center can then filter the full subject to include only those sections whose associated questions you answered incorrectly.
You can customize the Personalized Content by selecting or deselecting sections to include in the subject from the Summary page.
