Teaching Rationale And Relationship

The lectures provide core material and guidance for further reading. Tutorials reinforce self-directed learning while private study allows reading of material for advanced understanding.
Problem solving and examples are integrated into lecture and tutorial work. Practical clean room experience reinforces and enhances lecture material.

Assessment Methods

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