This CBT is divided into three frames: the control frame, the main frame and left-side frame.

• The control frame is at the top of the page; it contains the controls for maneuvering in the CBT.
• The mainframe is in the middle of the CBT. This is where the information from chapters and quizzes is displayed.
• The left side of the page serves as a hotlink that connects you to the beginning of the chapters.
