There are a few tools being used for class meetings. This article lists the instructions for Google Meet. Check with your teacher to ensure that you are using the correct platform.
Google Meet uses a Meeting Code to organize meetings. Your teacher may send you a link with the code embedded in it.
When you arrive in a meeting, your microphone may already be muted. If not, please Mute your microphone and wait for your teacher's instructions.
To mute your microphone, click on the microphone icon in the Google Meet window (see below)
When your microphone (or camera) is muted or turned off, it will turn red.
