Google Chrome allows users to have completely separate browser sessions for each Google profile you have. Each profile has it's own Chrome Sync, bookmarks bar, extensions, history, and preferences.

For school, you should have a single Chrome profile just for your JPIICardinals account. This prevents permissions errors and confusion between personal and school accounts.

When you first sign in to Chrome on your computer, it will create the first profile automatically. To add a second profile, click on your user icon in the top right corner and choose the "+ Add" option from the menu. This will open a separate chrome window and let you log in again to another account.
