WACE Maths Applications study guide
WACE Maths Applications · Work through your exam, one topic at a time.
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. Candidates should treat any such details as unconfirmed until they check the current syllabus and assessment documents on the SCSA Years 11 and 12 site. Preparation should begin with the current course syllabus and its dot points, followed by the school's assessment outline, then past ATAR course examinations that SCSA publishes, worked under timed conditions. Topics on this exam: Mathematics Applications. The WACE Maths Applications study guide has 1 section and about 331 words.
01Mathematics Applications: Working with Data, Percentages and Financial Modelling
Mathematics Applications rewards steady numerical discipline more than clever tricks. Across the syllabus you need fluency in data display and summary statistics (mean, median, mode, range, standard deviation, box plots, histograms, cumulative frequency), percentage change and the unitary method , ratio and proportion , and financial mathematics including simple and compound interest, appreciation and depreciation, and reducing-balance loans. You should also be confident converting between fractions, decimals and percentages, and reading tables and graphs critically. Percentage change direction: a 20% rise followed by a 20% fall does not return to the original value; multiply by 1.2 then 0.8 to see why.

- Practice questionsA dataset of 10 values has a mean of 24.
- FlashcardsSimple interest formula. Interest I = P × r × t, with P the principal, r the annual rate as a decimal, and t the time in years.
- Cheat sheetSimple interest: I = P × r × t, where r is the annual rate as a decimal and t is time in years; total amount A = P(1 + rt).
- Key termsBivariate data. Data recorded in pairs, where each item gives a value for two variables, such as height and arm span, so that the relationship between the variables can be examined.
- Study planBuild a one-page formula sheet covering consumer arithmetic (simple and compound interest, appreciation and depreciation, percentage change) from your own notes.
- Common mistakesStudents treat graph-reading as exact arithmetic and default to calculator-style precision, forgetting that a point located by eye carries uncertainty of roughly half a grid square, so the answer is over-precise and often outside the accepted range.
