Lean Six Sigma Yellow Belt certification exam have a specific format and that is of the multiple choice questions. If i had to clear the certification exam, then i needed to prepare on the similar structure or else there was no point of going through the mocks. And the mocks surprised me with the similar format consisting of the same number of questions divided in the similar time duration and performance judged on the same scoring system. How fun it was attempting the ICYB premium simulated tests online. I am glad that i could be a part of this revolution that has helped many make a career for themselves.
