The content of this module is delivered through lectures, module website, directed reading and tutorials. Students work on their understanding through a combination of independent study, preparation for timetabled activities, tutorials and problem classes, along with formative assessments in the form of coursework assignments. Students work on their practical skills, professional skills and technical understanding in technical and assessed laboratories.
