You can add certain specific secondary emails to you school issued Chromebook, specifically Cascadia Tech accounts (@student.evergreenps.org). To do this follow these steps:
1. Within Gmail click the account button in the top right and then click "Manage accounts" (can also find accounts directly in the Chromebook settings if you like)
2. Add your secondary account (note only certain accounts are allowed, not personal ones)
3. You can now switch between email accounts (and Drive etc) via the same account button in the top right.
Make sure that you are using your added Evergreen account if you are using Google Meet with Cascadia Tech. Your Woodland account will refuse to allow you in.
