Seneca's School sync will automatically create brand new classes in Seneca. These classes will mirror what is on your school's MIS, if there are any missing please speak to your Data/IT manager. Any previously created classes will be archived.
You should aim to use your new synced classes with the 'Synced' label.
You can still access & create classes using the manual method (for extra revision classes for example), or you can choose to archive them click here to view how.
