1. This is dependent upon the degree you take. Assuming you take B. Sci and not any other Science degree like B. Med Sci or B Adv Sci.
Code:
1. A student must complete 144 units of credit including 12 units of General Education.
2. The degree must contain a Major sequence of study and either a second Major or a Minor sequence.
3. A student must complete at least 36 units and no more than 60 units in Level I courses from at least three Schools.
4. A student must complete at least 24 units at Level I from Science Schools (defined as Schools in the Science Faculty plus those in other Faculties that currently provide programs under the authority of the Faculty of Science).
5. No student may commence Level II courses until 24 Level I units have been successfully completed.
6. No more than 18 Level 1 units of credit in any one subject are may be counted towards the completion of the degree.
7. A student must complete a minimum of 84 units of credit from Science Schools (defined as Schools in the Science Faculty plus those in other Faculties that currently provide programs under the authority of the Faculty of Science).
8. Progression to Stage 4 Honours is subject to academic performance. Students seeking to enrol in Honours are required to have the permission of the Head of School, to have completed all the requirements for Stages 1, 2 and 3 of the BSc and to have satisfied prerequisite requirements as specified. All General Education must also have been completed. Students who have not qualified for the BSc at pass level will not be permitted to enroll in honours.
9. A Major sequence is defined as: at least 42 units at Level II and III in a single discipline or area of study, including at least 18 units at Level III.
10. A Minor sequence is defined as: 24 units of credit at Level II or III. The Minor may either consist of courses available within but not taken as part of a Major or may be a sequence as defined in Table B.
11. Where a student does Majors in two cognate areas that have courses in common they may be permitted to count up to 18 units of credit towards each Major sequence, but only 6 units of credit may be at Level III.
2. Accordingly, if you are taking Level 2 or Level 3 Math courses, then you can head towards a minor sequence (This is not a Major Sequence). Then in answer to your question, Yes you can do so.
3. Before a student commences level 3 courses, he/she would have undertaken all the pre-requisite courses and/or at least 36 UOC for level 1 courses.
4. All level 3 courses that are taken, are rarely counted as your electives (courses you slot into your degree), you should use it either as a major OR Minor.
