Honours Calculation

COMP4801 Final Honours Grade will be used to record the Class of Honours and the Mark. The Honours Mark will be a weighted average percentage mark (APM) calculated by first calculating the average mark for 1000, 2000, 3000 and 4000 level courses. We denote these averages: A1, A2, A3, and A4, respectively. The averages are calculated based on all courses completed (including fails) that are listed in the program requirements, excluding non-COMP-coded electives, giving NCN and WN a nominal mark of zero. Finally, these averages are combined using the formula APM = (0.1 X A1) + (0.2 X A2) + (0.3 X A3) + (0.4 X A4).

 

The APM will then be used to determine the final grade according to the ANU Honours grading scale, found at http://www.anu.edu.au/students/program-administration/assessments-exams/grading-scale.

Admission Requirements

At a minimum, all applicants must meet program-specific academic/non-academic requirements, and English language requirements. Admission to most ANU programs is on a competitive basis. Therefore, meeting all admission requirements does not guarantee entry into the program.

The University reserves the right to alter or discontinue its programs and change admission requirements as needed.


Domestic applicants

Before applying for a program, you should review the general information about domestic undergraduate admission to ANU programs and how to apply, and the program-specific information below.

  • Applicants with recent secondary education are assessed on:
  • completion of the Australian Senior Secondary Certificate of Education (AQF) or equivalent, and the minimum Selection Rank (from their academic qualifications, plus any adjustment factors ) requirement for this program; and
  • English language proficiency; and
  • any program-specific requirements listed below.
  • Applicants with higher education study are assessed on:
  • previous higher education studies; or secondary education results if completed less than one full-time equivalent year (1.0 FTE) of higher education; or the result from a tertiary preparation program; and
  • English language proficiency; and
  • any program-specific requirements listed below.
  • Applicants with vocational education and training (VET) study are assessed on:
  • previously completed VET qualifications at AQF level 5 or higher (i.e. a Diploma or above); or secondary education results if the VET qualification is not completed; and
  • English language proficiency; and

The Bachelor of Advanced Computing (Honours) (BAC) is a unique, interdisciplinary program that will prepare you to be a future leader in technology.

The BAC can be taken as a single degree which includes a number of core and compulsory courses including a computing specialisation. The single degree also offers 48 units (eight courses) of electives that can be taken from additional computing courses (enabling you to complete a further computing major, minor, or specialisation), or a major from other schools.

The BAC can also be taken as a part of many Flexible Double Degrees.

+
+

Single degree

+

  • This degree requires a total of 192 units (each course is typically 6 units though some may be 12 units or higher)
  • There are a number of core and compulsory courses
  • You will need to complete one computing specialisation
  • 48 units (eight courses) of electives that can be taken from additional computing courses (enabling you to complete a computing major, minor, or specialisation), or from other university courses.
  • You can do a maximum of 60u 1000 level courses in your single degree

+

Double degree

+

  • There are no university electives available in the Flexible Double Degree.
  • This degree requires 144 units  of the compulsory Advanced Computing requirements (each course is typically 6 units though some may be 12 units or higher)
  • You will need to complete one computing specialisation
  • Typically you can do a maximum of 72u 1000 level courses in your Flexible Double Degree
  • You can find your Flexible Double Degree with the BSEng from Program and Courses

+

Enrolment Status

+

While it’s possible to enrol in fewer courses per semester, it will take you longer to finish your program and get your degree. There are maximum time limits for completion of the degree on a part-time basis. If you are an international student you must always be full-time.

+

Important things to keep in mind when choosing your 1000-level courses

+

  • When you enrol for the first time you will typically study '1000-level' courses. These courses have '1' as the first number in their course code, such as COMP1100.
  • You need to enrol in courses for both First Semester and Second Semester though note that you can change your Semester 2 courses all the way until July.
  • You can’t study more than four courses (24 units) per semester, making 48u for the year, and international students cannot study less than 24u a semester except in exceptional circumstances and with approval.
  • You may take 1000-level courses later in your program. But remember you can’t count more than ten 1000-level courses (60 units) towards your single degree or six 1000-level courses (36 units) towards the BAC half of the Flexible Double Degree.
  • In choosing your first year programming courses you will have a choice of doing COMP1100 or COMP1130 in Semester 1, and COMP1110 and COMP1140 in Semester 2. The standard courses are COMP1100/1110 but if you have a strong maths background, and/or significant programming experience, you might like to choose COMP1130/1140. Note that if you choose 1130 you will be able to drop back to 1100 in the first 12 weeks.
  • You should make sure you do MATH1005 and COMP1600 in your first year.

+

Majors and Minors

+

+

Electives

+

If you are in the single degree then in your first year you have two computing electives and two university electives to choose.

  • To find 1000-level (first year) elective courses, use the catalogue search.
  • University electives can be additional computing courses, or courses from anywhere in the university.
  • Courses that can be taken in first year as computing electives are: COMP2620 and COMP2400 . Students should consider these in light of their performance in their first semester computing and maths courses and take them only if they have performed well.
  • If you enjoy and are good at  mathematics and do not plan to do a major from another area of study, then you are encouraged to consider doing the following:
    • Semester 1: MATH1013 Maths and Applications 1, or MATH1115 Maths and Applications 1 (Hons) (only recommended for outstanding maths students)
    • Semester 2: MATH1014 Maths and Applications 2, or MATH1116 Maths and Applications 2 (Hons) (only recommended for outstanding maths students)
  • Suggested university electives in your first year if you are interested in Engineering are: Semester 1 - PHYS1001 or PHYS1101  and Semester 2 – ENGN1218
  • Suggested university electives if you are interested in Information Systems are Semester 1 or 2: INFS1001
  • If you have an interest in another area (eg management, mathematics, psychology, languages) then you should explore first year courses in these areas and in particular, look at the majors and minors in these areas. These will give you an idea of the first year courses that you should study.
  • Transdisciplinary (TD) Courses can be found on P&C. By following your degree rules you will meet your TD program requirement.

Corequisite majors: Mathematics; Mathematical Economics; Mathematical Finance; Mathematical Modelling or; Quantitative Biology


Mathematics is the study of universal patterns and structures; it is the quantitative language of the world; it underpins information technology, computer science, engineering, and the physical sciences; and it plays an increasingly important role in the biological and medical sciences, economics, finance, environmental science, sociology and psychology.

The Mathematics and the Mathematical Modelling majors are designed to provide a foundation in Calculus, Linear Algebra and basic modelling techniques through the course in differential equations, which then lead onto a broad choice of mathematics courses in later years.

The Advanced Mathematics specialisation is an extension of these majors, ensuring that students undertake the foundational courses in analysis and abstract algebra, and later year advanced courses which form the basis for research in mathematics, in both the applied and pure mathematics. Successful completion of this specialisation, along with the co-requisite majors provides the basis for progression onto Honours in mathematics. 

+
+
