Please use the "Search" bar within each file holder to search for your teacher by last name. Teachers are also sorted into relevant shop or academic department folders.
If you search by Teacher Name: To clear the search bar, click the red 'X' next to the bar once you are done. This will bring you back to the main level.
If you search by Subject Folder: To move backwards to get to the main level, once you are directly in a folder please either click the folder you are in again to close it OR click "Document Container" in the upper left.
