Bachelor of Psychological Science (BPsySc) is a 4-year APAC accredited sequence in psychology. In the first 3 years you study a broad mix of courses in psychology and in the 4th year you do a thesis as well as coursework. When finished, you are qualified for provisional registration as a psychologist or entry into postgraduate programs in psychology.
The Bachelor of Arts (BA) and the Bachelor of Science (BSc) both comprise a 3-year undergraduate APAC accredited sequence in psychology. The difference is that one is taken through the Arts Faculty and the other through the Science Faculty, and these Faculties have different additional requirements (for instance, in the BSc you must take some basic science courses as well as psychology). The BA and BSc sequence of courses in psychology covers a broad mix of topics in the field.
You will take courses that make up the APAC-accredited sequence. Most of these courses are also undertaken in the BA an BSc extended or double major. BPsySc students also take some additional psychology core courses that are only available in the BPsySc.
If you want to be eligible to apply for Honours in Psychology (and ultimately be eligible for professional registration as a psychologist) you should take an extended or double major in Psychology and follow the APAC-accredited sequence. Otherwise you can undertake a single major in psychology to learn about the human mind and behaviour.
Psychology can also be studied through BA and BSc dual degree programs. The psychology courses that you will need to take will be the same as in the single degrees, but your course will be structured differently to take into account the other degree. Please consult myAdvisor for further information on dual programs.
