You can copy and transfer your school's Google account files to another Google account (such as your own personal Google account). This process lets you:

  1. Back up your files from time to time.
  2. Keep important files when you graduate, switch schools, or leave for another reason.

Please follow this link's directions on how to make the transfer: https://support.google.com/accounts/answer/6386856


You can also download your data instead if you do not want to transfer to another Google account.
