I was just going through both the melbourne and monash websites
but an honours degree and postgraduate diploma are different (in name only at monash a different faculty handles both but didnt check melbourne)
"The course structure for both fourth year courses is the same, and involves the completion of three compulsory subjects (which includes the research project), and two elective subjects."
these are just snippets i found at the melbourne site if you look here
https://handbook.unimelb.edu.au/view/2011/BH-SCI#structureIdscroll down to psychology
"In addition to satisfying the BSc (hons) entry requirements, students interested in entering the Psychology program will need to have a major in Psychology with a weighted average of at least H2A (75%) in second and third-year subjects within the Psychology area of study, or equivalent. In computing the weighted average, second year subjects are normally assigned one-third of the weight of third-year subjects."
"Entry into an Honours program is subject to the capacity of the department(s) or schools(s) offering the program to provide adequate supervision in a project appropriate to the interests and preparation of the individual student.
d. For entry to the BSc(hons) in 2011 and 2012 only, the Selection Committee is permitted, at its discretion, to evaluate an applicant’s ability to pursue the course successfully using, as an alternative to the normal criteria,
• an undergraduate degree as detailed above, with a major relevant to the honours discipline into which entry is sought, with an average of at least H3 (65%) across 87.5 points of third-year study.
Selection is not automatic and in particular is subject to competition, to any relevant quotas, and to the availability of supervision and resources in suitable project areas."
"Students are ranked for selection according to the index and the highest ranked students falling within the agreed quota are recommended to the Faculties for selection. It should be noted that students are only considered for selection if the credit-point weighted average of all second and third level psychology subjects is at least 70% (when converted to the University of Melbourne scale)."
eh just email them lol melbourne site sucks
