WACE Maths Applications case studies
WACE Maths Applications · Put your knowledge to work in context.
The Western Australian Certificate of Education (WACE) is the senior secondary credential issued to students in Western Australia, and Mathematics Applications is one of the mathematics courses students can take within it. The School Curriculum and Standards Authority (SCSA), the statutory body whose website is summarised below, publishes the curriculum, assessment and certification information for Western Australian schools, including the Years 11 and 12 senior secondary pages where course details live. The overview page you are reading is an independent study resource and is not affiliated with, endorsed by, or operated by SCSA. Because the source text retrieved for this page is the SCSA home page rather than the Mathematics Applications syllabus, no course-specific figures - assessment weightings, examination duration, number of questions, or mark allocations - are stated here. The WACE Maths Applications case studies are 5 cases and about 3,197 words.
