The main course for a section is the course that students are automatically taken to every time they log in to CodeHS.  

To change a section's main course, click on the three dots to the right of the course and select "edit course."  From there,  you'll find an option to change the main course for that section. Choose the course you want to appear as the main course and click on "change." The selected course will now be the default course.
