The course is divided into four units and some units are further divided into sections. You can navigate through the materials using the navigation block to the left of the main content (screenshot shown here on the right). This will show at least the unit you are in, and the pages within it. Clicking on a unit title that has a downward arrow will expand to show the content. Clicking on a topic title that has an upward arrow will collapse the content that is already showing to make it easier to navigate to the next unit.

The material consists of textbook-style sections, supplemented with video presentations. At the end of each section is a short quiz where you can test your understanding of the material that has been presented.

Where links are provided to other websites or materials, these will usually open in another browser tab. However, you can force this behavior by holding down the control (Ctrl) key on your computer keyboard at the same time as clicking on the link.
