After you graduate, your Google Apps for Education account (including your email, docs, spreadsheets, slides, shared docs, etc...), and your Schoology account will be suspended.

If you wish to keep items that you created and saved using these tools, please download those items to another storage device or program (thumb drive, or ownership transferred to a personal Google Apps account).

 

Your best option is to download your Google Data using Google Takeout. Here is the documentation explaining how to use it along with a tutorial below.
