Teaching Rationale And Relationship

The online sessions provide core material and guidance for further reading. Workshops reinforce self-directed learning and private study for advanced material.

Alternatives will be offered to students unable to be present-in-person due to the prevailing C-19 circumstances. Student’s should consult their individual timetable for up-to-date delivery information.

Assessment Methods

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