As a teacher, you have the option to specify which subjects you teach via My Settings. You will then get shortcut buttons in the Skolon App Store to tools within your subjects.
Click on the profile icon in the top right-hand corner. Click on My Settings.
Search for one of your subjects, click on the magnifying glass and then on the subject.
Repeat until you have added the subjects you want shortcut buttons for. Buttons for a maximum of 3 subjects can be displayed.
In the Skolon App Store, you will then see shortcut buttons for the subjects you have specified.
