Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

A test of design checks whether a control, if operating as intended, would prevent or detect a material error. A test of operating effectiveness checks whether the control actually operated consistently over the period, usually by examining a sample of occurrences.
