Watch this video for the steps to change the language for your Google Classroom Account.
If you have two Google Accounts, one for home, and one for school, you'll want to manage them to choose "SYNC is ON" so you can sync and not bounce back and forth between the two accounts within the same window.
Always keep the two accounts separate. Don't try to open extensions in one to use in the other, this is when you will lose forms or docs in the middle of something important.
Choose a different image for your Home account and your school account to stay organized. Here you will see Mrs. Thrash has a home account and a school account in Google and keeps the two in separate windows. This is easy if you have an image to differentiate.
Only have tabs open for the class you are attending or work you are doing now: "5 tabs max" is a good rule
Make sure you have only one instance of each file open
Once you open a form, only be in that tab until you've finished and have hit submit.
Use Chrome Browser
Close all tabs and shut down devices each night.
Save a backup of any files you submit, you can ALWAYS email to teachers. ;)
Stay organized with your files in case you need to resend and assignment!
Make sure the name of the file is specific so you can find it easily later
Create a folder for each of your classes, and put files in the correct folder for easy access
Email files if needed
