Still studying but the DOE questions here are leveling me up fast.
Honestly, the regression and ANOVA sections of the ICBB are no joke - I struggled with those here too. But working through the wrong answers with explanations was more useful than just reading theory. Passed with confidence and already applying it in my supply chain role.
Career-switching into quality engineering, the ICBB felt intimidating at first. Drilling the MSA and Gauge R&R questions here made the real exam feel manageable.
I spent months preparing for the ICBB and these practice questions were the last piece of my prep. The Analyze phase digs deep into hypothesis testing and regression, and the coverage here reflects that difficulty honestly. Got certified and it opened doors I did not expect in my career.
