A zApp Book is a collection of multiple zApps, which may be divided into chapters based on theme, or any method of classification and division that the zApp Book author desires.
Progress
Progress indicates how much of the zApp Book you have completed. If it is yellow you still have some more to complete. If it is green then you have completed the zApp.
Time Left
Time left is the amount of days and hours you have until the zApp Book is due. After this time the zApp will no longer be open and your results will not be stored. If you have failed to complete any zApps or zApp Books by the due date please see your teacher.
Assigned By
This field shows you who has assigned the zApp to you. If there is no name it is a zApp Book you have added to My Library.
Shelf
To help organize your work, there is a shelf feature. You can add work to specific shelves like Maths Homework or Things due on Monday, by selecting the blue and white button in the action column. You can create new shelves and organize your zApp Books into convenient groups.
Archive
To remove a zApp Book from your library you can select the red button from the action column. zApp Books are never deleted, they are moved to the Archived zApp Books tab and can be accessed at a later date.
