1- Click on the Courses tab. The courses showing here are the ones you have already selected to be visible in the Dashboard. To manage the courses, click on "All Courses"
2- You are able to see all your current courses and the Past courses, only if they are been published by the Professor. You can select which courses to show in the dashboard clicking in the star symbol next to the course. If the star has a colour that means the course will show in the Dashboard.
