Simple familiar questions show the procedure in the way they are asked. Complex familiar questions join several ideas, sometimes from different topics. Complex unfamiliar questions do not say which procedure to use, in a setting you have not practised. Across the examination, about 60% of the marks are simple familiar, 20% complex familiar and 20% complex unfamiliar.
A QCAA-approved scientific calculator, and the formula book, which is provided. No notes. A scientific calculator's statistics mode gives Pearson's correlation coefficient and the least-squares line from raw data; financial questions are worked with the formulas.
