In the case of Year 12, you cannot change courses, but you can withdraw from them. An extract from a Board of Studies information booklet:
"Early in the year your school will submit an entry to the Board showing those courses that you expect to complete that year.
If you wish to change courses after the entries have been submitted, you need to apply to the school principal.
In the case of Preliminary courses, the principal will allow a change of course provided that he or she is satisfied that the student can satisfactorily complete the new Preliminary course before commencing study of the HSC course.
Student studying an HSC course may not change course unless the principal is satisfied that they:
- have satisfactorily completed Preliminary component (or equivalent) of the course they wish to enter
- will be able to complete all HSC course requirements, including assessment.
Contact your Year Adviser, principal or Board of Studies Liaison Officer for a full explanation about changing courses."
