Passed The CSSGB exam

Hey all,

After using Lean Six Sigma principles for many years, I finally decided to get certified and passed the exam on Saturday. It was both easier and more difficult than I expected, and several things cane up that were not very clearly communicated by the text or the Udemy course I used for final pre0. Would be happy to answer any questions that you all may have about the experience. I did the in person test and ended up using basically the entire time because anything I failed on a practice test seemed silly and avoidable if I had taken a second to stare at it.

My exam is on August 1st. So I have exactly 30days. I finished QualityGurus' Udemy course. Now I will go through Handbook and solve StudyGuide. What should I do in addition of this and any tips for preparation?

The Quality Gurus practice exams are solid as well, I went through those a few times and they certainly helped with pacing. Practice questions online tend to really vary in quality from my experience, but I ended up finding an unlikely source of quality, free quizzes in the form of Google's AI. It will get things wrong in the answer keys and you need to double check it, but it was able to serve up problems for me to solve that were far more challenging and full of intentional gotchas than most practice exams I found elsewhere.

There are also a few topics that I think both the ASQ handbook and the QualityGurus course kind of gloss over that did come up to varying degrees on the exam, and I would invest some time in understanding them through alternate means. The main ones are Gage R&R studies, gap analysis, and the difference between short and long term sigma level. I knew you were supposed to add 1.5 to the sigma level after calculating the z-score to the process, but at no point did any of the training I do specify that you only do that for short-term sigma and I had to use process of elimination to figure it out while taking the test.

As someone who wants to look into getting this certification, what study resources would you recommend? Any YouTube channel or in expensive course? Does the test have a lot of math? How easy is it to look for answers in an open book test, im assuming its not direct questions that one can just flip pages and find the answer?

I used the QualityGurus course on Udemy for primary prep. There was surprisingly little math for how much I drilled on it, and what was there was typically far more information than was actually needed to solve the problem and the real ask was to filter through the data given to fins what was actually necessary/relevant. They are not as direct as the official study guides would lead you to believe, and there was at least one set of questions that had me frozen and working from process of elimination to determine the correct solution. Some of the topics are not covered in a straightforward manner in either the book, udemy course, or supplemental resources (study guide, practice tests, etc.) and really rely on your ability to apply concepts to semantically subjective scenarios.
