In the top right of the screen under the red bars, check the box “Show courses with no sections.” The list will then include courses that have not yet been offered.
Double click on the course you wish to offer.
Click on the green plus sign to the right of the line.
In the editing window, enter the instructor’s name and the meeting schedule.
It’s also important to add the maximum enrollment number (this can be changed), whether the instructor wants to grant enrollment permission, and whether there will be a final exam during the final exam period. You can add course attributes too.
