Class folders are a great way to keep relevant assignments together in one place. If you already have them setup, you can create copies of the folder and the assignments within them to use in other classes.
Here's how you can do that:
Go to any class where you have class folders
Open any class folder
Tap the wrench icon
Choose Folder Settings
Choose the Copy Folder option
Select any number of classes you'd like to copy to
Tap Copy Folder
Pro Tip: On iPad, you can also long press the folder itself and choose Copy Folder from the contextual menu that pops up.
And that's it! Want to keep your list of class folders and assignments organized? Check out this guide!
