Ditto what -may-cat says. The Hons bit in the title just means it's set up as a 4 yr degree, but wherever you go and whatever major route in Psych you take you need the same GPA (or WAM, whatever) to get into Hons. Some places have a quota on Hons (USyd I think for example) so you don't actually know what the target is to get in from year to year. Other places (UNSW, for example) have a cut-off mark so at least you know what to aim for. But the main point is it doesn't matter if you do an accredited Psych major as part of a BPsych(Hons), part of BA, BSc, BPsychSc - in all cases you will need to pass some hurdle (and it will be the same for all majors) and then you can get into Hons. If you don't make it into Hons, even in a 4 yr Hons course, you will be transferred to a three year degree (like a standard BSc or BA) and will graduate without Hons. But conversely both BA and BSc can let you move to Hons if you get the marks and you'd graduate with BSc(Hons) or BA(Hons). There really is no difference between 3yr and 4yr degrees as long as the three year degree has a route into Hons (which all do). If you want a professional masters in Psych you need a Psych hons or the equivalent (e.g. UMelb offers a postgrad diploma that is Hons equivalent), otherwise you can't get on the course.
