Questions on any part of the unit should be posted on the Teams channel — turn notifications on. Apologies, but there are 260+ students on this unit and individual emails and DMs on one-to-one queries usually won't get a reply; posting publicly means everyone benefits from the answer. No access to the Teams channel? Contact COMS Student Enquiries.
