Begin by clicking on the course selector icon (looks like a waffle iron) at the top of the page.

Next, click on the pin to the right of the course you want to rise to the top of the list.

Reload the page. When you click on the course selector again, the course will be at the top of the page.

Once you pin a course with the course selector, you can pin courses with the My Courses widget. Scroll down on the organization homepage. Hover over the course you'd like to pin and click on the ellipses.
