Some institutions may configure classes to be viewed in real-time, while they are happening. These are called LIVE classes.
Watching classes live is very similar to watching recorded classes except that you can't control the playback (fast forward, rewind, pause). Unless you've invented a time machine, in which case we'd love to hear more about it...
To access a live class:
The classroom toolbar appears across the top of the screen, allowing you navigate out of the classroom, open the Notes panel, or open/close the Questions panel.
