If you miss a live lesson, or the timing isn't suitable to you or your class, you can watch lessons on catch-up by visiting the individual live lesson page.
The catch-up lesson will normally be ready in an hour or so after the end of the broadcast, but archived lessons can take until the next day to process fully.
You will need to be logged into your account to view live lessons on catch-up.
Notes
When watching a lesson on catch-up some of the interactive functions will not work, such as the polls and Q&A.
Even if you cannot join live, classes can still submit questions in advance.
