This is a great course for an MBB review and certification. The program is accredited by the Council for Six Sigma and it involves a project to ensure knowledge retainment and practical experience. The learning platform is easy to use and the contents are well laid-out, which made it easy for me while managing work/life. The statistic portion is presented in a laymen's term, which made it understand. Anther aspect that was helpful is the 3 different modes for review. This is a great investment. I've compared other similar programs out there (online and traditional method), and this one is by far the one of the best and most practical, but without compromising content/subject. One thing I would improve is to add a bit more clarity on the project requirement/expectation. I suggest to clearly state the DMAIC framework as a basic expectation for the project outline/delivery, since projects are not same and students come from different background.
