I think the lecture is not quite useful but the tutor is. The tutor, Michelle Song, gave us number of notes and help you understand more. Besides, it is easy to get high marks if you understand all the materials and try to finish all the tute questions.

lecturer was extremely helpful, all the handouts were relevant to the exams. more than sufficient materials for the exam and excellent lecturers mikhaella and edwin, dayani is ok in comparison but overall its a great unit to take
