Teaching

Tuesdays 8:30 am - 9:30pm

Thursdays 11:30am – 13:30pm

The course is taught through lectures, class discussion and weekly tutorials to enhance students’ understanding of topics treated.

Formative coursework

There will be at least one major interim assessment (IA) and a final exam at the end of the semester. Students are expected to undertake presentations which will contribute to their final grades. The IA will be on the materials covered during lectures. Success in this course depends on reading widely on the topics to be treated, and is highly recommended.
