If you need to adjust the topics for all classes with the same scheme of learning, for example adjusting the topics or turning homework on or off for a week, you can edit and then republish the scheme.
Note that this will override any changes made by individual class teachers in the Planner page.
It will also only affect future homework. Homework that has already been set will be unchanged.
To edit a scheme:
go to the Scheme of Learning page (Management -> Scheme of Learning).
Select the scheme you would like to edit
Click Make changes
Make changes, e.g. adding topics or turning homework on/off
