To add a new subject, login as an Administrator and go to the settings tab.
Click on the button, which will display the Add a new subject popup, where you can type in your subject name and click create to save the subject. This subject will now be available to all of your teachers across your school.
Subjects can be named anything that you want. If you are a sports teacher and you want to share a training brochure to everyone in your team, you may want to have a subject called: Sports training, or Athletics. If you have multiple modules within a subject, you can even use a naming convention e.g. Biology - Photosynthesis, Biology - Internal systems.
