Courses are broken into Modules and pages. You get to the modules by clicking on the course under your curriculum page then going to the bottom of that page. Once inside a course, at the bottom of each page you will see < Previous Page and Next Page>. This allows you move move serially through the course. Also you will see a table of contents button at the top right. There you can jump around the pages inside a module and also jump straight to the module test.
