The content of this module is delivered through lectures, module website, directed reading, pre-recorded materials and practical sessions. Students work on their understanding through a combination of independent study, preparation for timetabled activities and tutorials. Students work on their practical skills and professional skills through laboratory sessions and discussion tutorials.
