. to effectively use the academic staff resources provided (consultation time, tutors, e- mail etc)
. to participate as an effective and honest member of a learning team
. to contribute effectively to a group of peers in a climate of mutual respect and to question each other and the academic staff when uncertain

This course is graded as Competent or Not Yet Competent and subsequently the following course grades are allocated:
80 - 100: CHD - Competent with High Distinction
70 - 79: CDI - Competent with Distinction
