Preassessment and Postassessment
The Preassessment provides you with an overall assessment of your strengths and weaknesses prior to starting this course, and includes specific recommendations on how to use the course content to attain mastery of all of the concepts treated here. The Postassessment has a similar form and purpose but is designed to be used after you've completed the course.
Each assessment presents 50 multiple-choice questions covering the core content of each section. After you complete these assessments, you can review and print the answers if you'd like.
The Postassessment is completely optional. If you choose to take it, you can do so at any time. However, you should not attempt the Postassessment until you've finished the course; you can think of it as a "final exam" of sorts.
Each course is divided into sections (presented in the left-hand navigation) with multiple topics (which are displayed when a section is opened). The topics present course content information in the form of text, animations, links to optional readings, and video clips. Each course topic also offers many practice opportunities, which are explained further below.
