University of Western Australia
The university also offers the Bachelor of Philosophy (BPhil) course for high-achieving new students. This is a research intensive degree which takes four years because the honours year is an integral part of the degree (most other degrees last three years with the honours year as a separate degree). Students studying the course choose disciplines from any of the four bachelor's degrees. Places are very limited with on average only about 30 places offered to students each year. Thus there is a lot of competition for places and the cut-off admission rank is very high.
Postgraduate education
For example, astronomy degrees take five to six years on average, but observational astronomy degrees take six to seven due to limiting factors of weather, while theoretical astronomy degrees take five. Though there is substantial variation among universities, departments, and individuals, humanities and social science doctorates on average take somewhat longer to complete than natural science doctorates. These differences are due to the differing nature of research between the humanities and some social sciences and the natural sciences, and to the differing expectations of the discipline in coursework, languages and length of thesis. However, time required to complete a doctorate also varies according to the candidate's abilities and choice of research. Some students may also choose to remain in a program if they fail to win an academic position, particularly in disciplines with a tight job market; by remaining a student, they can retain access to libraries and university facilities, while also retaining an academic affiliation, which can be essential for conferences and job-searches.
