This practice exam draws 150 questions, 30 from each DMAIC phase, from a 300-question pool spanning every Yellow, Green and Black Belt lesson, shuffled in both question order and answer order every time you sit it. It matches the real IASSC Certified Lean Six Sigma Black Belt exam's question count, time limit, and 70 percent pass mark.

Rules
