Hi mcpueblo, 

I looked into what you described and can see that the course Art History is not available to be added to a class at this moment. However, the content can still be assigned manually without the need for the course to be added in the Class subject line.

I’ve outlined the steps to go about doing this here:

Step 1:

Go to the search bar at the upper left-hand side of your screen and type in the name of the course needed (on the screenshots below, I am using the High School Geometry content as an example).

Step 2:

After you go to the page you can view the content, and then click on the topic that you want to assign content from.

Step 3:

Once you have chosen the exercise you want, click on it and the following page will appear to assign the content to the corresponding class

Step 4:

From here, you can choose which class you assign it to, the due date and if you assign it immediately or save it for later use.

Step 5:

Click on Assign or Save to complete.

I hope this helps!

Best, Jo
