For Students-Using Google Classroom
Access your work from Google Classroom, NOT from the "Classroom" folder you will see in your Google Drive. Leave that folder alone!
Using Classroom on your phone: The Classroom app is available for iOS and Android devices. To use all the features of the Classroom app, you need to download Google Docs, Sheets, and Slides as well.
NOTE: You should complete assignments in the CLASSROOM APP, not from the Classroom folder in Google Drive.
