I am a learner and have been one for a very long time. My mother used to tell me how I used to get stuck to questions till I got a satisfactory reply. ICBB certification exam is one such thing that has happened to me since my childhood that has stayed with me throughout. I remember I had taken up the IASSC Certified Lean Six Sigma Black Belt premium question bank to prepare for the exam. It so happened that I got stuck in one of the topics and started wondering what will happen now. But soon after, I was bombarded with more questions and my doubts resolved through practicing on them.
