This mock follows the style of the Tableau Desktop Specialist exam: mostly multiple-choice questions on connecting to data, exploring it, building charts and sharing, plus a few hands-on builds. The questions are our own, and it's practice, not an official exam.
You have 40 minutes for all twenty; the clock shows above the worksheet and keeps running between questions. Answer every question: there's no penalty for a wrong answer, so never leave one blank. If one takes too long, make your best choice and move on.
