You won’t normally have to be online at a specific time. Your course material is available for you from the beginning of each teaching period and you can work through it in the hours that suit you.
There are some live webinar sessions that run approximately once a month. These are a special opportunity for students to sign in at the same time as their tutors, normally before an assessment deadline. It gives you the chance to ask any questions relating to the assignment in real time and hear other student’s questions and thoughts. We understand that students won’t always be able to make these sessions, so they can be replayed the next day.
