A timed practice exam in the style of PL-300: 60 questions across the four skill areas (prepare the data, model the data, visualize and analyze, manage and secure), mixing multiple choice with tasks you do in the report. The timer at the top runs for the whole exam; it doesn't stop you, so you can still finish and review. Questions are our own, written to the published skills outline. Treat a result under 70% as a sign to revisit the units the wrong answers come from.
