About this course

Exclusive to high-achieving students with an ATAR (or equivalent) of 98+, the Bachelor of Science and Bachelor of Advanced Studies (Dalyell Scholars) program is an opportunity to challenge yourself alongside your most promising and talented peers.

The Dalyell Scholars program allows you to collaborate and network with like-minded world influencers.

In your first year, you'll gain essential knowledge in the fundamental sciences with broad subjects, including mathematics, and the option to choose units outside of the sciences. In second and third years you'll specialise in your chosen program with the option to take subjects from across the University. Throughout the four years of the Bachelor of Advanced Studies you'll complete a second major and get involved in cross-disciplinary, community, professional, research or entrepreneurial project work.

Throughout your degree you will also undertake exclusive Dalyell units of study that cover research showcases and methods and give you an opportunity to mentor.

In addition to completing distinctive Dalyell units of study with other high achievers, you will have access to enrichment opportunities including:

  • acceleration to master's level study
  • exclusive research and entrepreneurship programs
  • direct access to industry-based project learning
  • tailored mentoring and professional skills development to enhance your study and career opportunities
  • international experiences to develop your global perspective, including a global mobility scholarship.

Also available within the Dalyell stream is a special program in mathematical sciences for students who are looking for a career in maths and statistics.

Bachelor of Advanced Studies Streams
You can undertake the 'parent' version of the Bachelor of Science and Bachelor of Advanced Studies, or you may be interested in undertaking one of the streamed versions of the course:

For your second major you may wish to select your subjects from our academic schools:

In the final year of your degree, you have two options, Advanced Coursework OR Honours:

  • Advanced Coursework: Enhance your leadership, critical thinking and problem-solving skills and increase your employment prospects. You will undertake challenging coursework and a substantial real-world project individually or in collaboration with other students.
  • Honours: Develop deep analytical skills and prepare yourself for further research opportunities, such as pursuing a PhD. You will undertake a supervised but independent research project as well as connected discipline-based and/or research-focused coursework. Admission to the honours pathway is subject to meeting the specified WAM and additional entry requirements. Check with your faculty for details.

Subject areas

You are required to choose one major from the faculty listing below and a second major or minor either from your faculty options or from our shared pool of majors and minors.

Honours subject areas: Only available to students who meet the eligibility criteria for the honours pathway. Minimum WAM and additional entry requirements apply.

What you'll study

You can undertake the Bachelor of Science and Bachelor of Advanced Studies (Daylell Scholars) full-time over four years or part-time over eight years.

To complete the Bachelor of Science and Bachelor of Advanced Studies (Daylell Scholars) you must complete a total 192 credit points (cp) worth of units of study. A typical unit of study has a value of 6cp. Full-time students normally enrol in 48 cp worth of units each year. Each student is required to complete two majors, at least one from Science Table A.

The combined degree incorporates either an embedded Honours program of study for those who qualify or 4 x 4000-level coursework and project units that deepen your knowledge of your discipline area(s), and provide further experiential opportunities such as research, industry, or community related projects.

Science Daylell scholars will also offered the opportunity to complete 12 credit points of distinctive Dalyell units of study within the degree. This will include 2 x 2cp showcase units, a 6cp Research Methods unit and either a 2cp mentorship or research project. Dalyell Scholars in Science will also tailor their own suite of enrichment opportunities, from: acceleration within their major or to masters level study in the student’s discipline; additional third level and fourth level enrichment units of study outside of the student’s discipline; mentoring and professional skills development; a global mobility experience and access to high achiever programs in mathematical sciences.

You may exit Dalyell stream at any time and an average mark of 75 s to be maintained for progression through the degree in the Dalyell stream.Should the average not be maintained, students will be moved out of the stream but remain in the Bachelor of Science and Bachelor of Advanced Studies.
