Every session gets a read-only record once it has happened. It shows what the tutor covered, in the order they covered it.
What it shows
The record lists the tutor's feedback and any work set, then the boards: every worksheet page, question and whiteboard put up during the session, as they looked at the time, including marks and the explanation behind any revealed answer. Nothing on it can be changed afterwards.
Finding it
On the My sessions tab, each past session has a Record button. The feedback email links to it too. If nothing was put up during a session, the record shows just the feedback and any work set.
Reading it with the feedback
See Feedback and assigned work for the tutor's write-up and the tasks they set.
