##### Teaching Rationale And Relationship

Lectures provide core material and guidance for further reading. Problem solving is introduced through lectures and practiced during tutorial sessions. Laboratory sessions provide an opportunity to gain practical experience of the application of the application of techniques introduced during lectures.

#### Assessment Methods

The format of resits will be determined by the Board of Examiners

##### Assessment Rationale And Relationship

The examination provides the opportunity for the students to demonstrate their understanding of the course material.
The case study/ problem solving aspects of the assessment enable the students to demonstrate that they are able to apply this understanding and their analysis and synthesis skills to specific problems. The laboratory report provides the opportunity for the students to demonstrate an in-depth understanding of selected topics.
