Made me more powerful in the syllabus

Ah! Those days when i was struggling to find a good resource were such days. Yes, it was a struggle but now when i look back i realize that everything happens for good. I tested so many resources and could not zero in on a single one. Then on some stranger’s suggestion whom i met on the bus i tried the demo test and chose the ICBB paid service online question bank that helped me learn the practical application of the concepts of the syllabus of the IASSC Certified Lean Six Sigma Black Belt certification exam and i knew exactly how to answer the certification questions.
