From your profile, you can create a list of the courses in which you are interested, to have them always at hand.
Creating your list is very simple, just go to the My lists section in your profile.
Then, click on Add New List. You can add a title to your list, as well as choose whether you would like to keep your list in public or private mode.
Once you've done this, you can create different lists with the courses you want.
You can create as many lists as you want and add the courses directly from the course directory (without re-entering your profile) by clicking on the +Lists icon that appears when you hover your cursor over the course.
