As a Show My Homework administrator, you can amend or create your school's subjects under the Subject list section of the Admin tab.
Add a new subject at any time by entering the name of the subject in the text box and pressing Create subject. Teacher will be able to use this new subject immediately.
Press the next to the subject to change the name of it, if necessary.
Press next to the subject to delete the subject if you do not want it to appear on the subject list drop-down any longer.
If you have two similar subjects that you would like to combine, you can merge them.
Pressing Merge will bring up the following side panel for the subject you have chosen to merge to allow you to chose another subject to merge with.
For example, you may want to merge the subjects "Biology AS" and "Science". By clicking Merge next to "Biology AS" you would then be able to select "Science" from the drop-down menu. Pressing Continue will merge the two subjects under a single name. In this example, "Biology AS" will be merged with "Science" and homework marked as "Biology AS" appear under "Science" after the merge.
