Assessment Rationale And Relationship
The examination provides the opportunity for the student to demonstrate their understanding of the course material. The problem solving aspects of the assessment enable students to demonstrate that they are able to apply this understanding and their analysis and synthesis skills to novel situations. Laboratories provide the opportunity to assess practical skills and the application of theoretical knowledge.
