You can also open a test classroom at anytime on Spires by clicking on the 'Classes' tab on the navigation bar and then clicking 'Open Classroom'.
This can also be done, but appears slightly differently if you have a scheduled class already.
Clicking the open classroom button will give you the option to 'Test Classroom'.
Clicking on "Test Zoom" will take you to a dummy Zoom video call, where you can configure your audio and video settings.
*** We highly recommend you do this before your first class ***
This allows you to check Zoom is working normally on your computer and also configure your audio and video properly.
