A timed assessment can reveal a rule you knew but applied too quickly. Use this untimed review to separate the population, the calculation and the output. A weighted share uses amounts in its denominator; a count uses records. An overlapping condition needs one inclusion decision per row.
These questions use a fresh fictional support export and revisit the advanced assessment skills. Work through each task without the clock. The hints are available after you make an attempt. When a formula spills, inspect the whole result, including ties and empty groups. The final answer should explain its relationship to the source through references, so it remains useful after the export changes. No new function is introduced here.
