SACE Stage 2 Essential Mathematics · Put your knowledge to work in context.

SACE Stage 2 Essential Mathematics is a Stage 2 subject within the South Australian Certificate of Education, listed among the Stage 2 subjects offered by the SACE Board of South Australia. It is designed for senior secondary students completing the final stage of the certificate, including students in schools that deliver the SACE within South Australia and, through SACE International, in accredited schools outside Australia. The SACE Board notes that some Stage 2 SACE subjects have examinations as part of their assessment; whether Essential Mathematics includes an exam in a given year is something students should confirm with their SACE coordinator or by using the subject search, because the public exam pages do not name individual subjects. Examination formats across Stage 2 subjects may be paper, electronic, or oral. The SACE Stage 2 Essential Mathematics case studies are 5 cases and about 2,655 words.
