Easy Guide: ICBB IASSC Certified Lean Six Sigma Black Belt: Questions and Answers

In 2017, this were great, but now Mid of 2020, This is NOT accurate anymore.

There are many things wrong with the purchasing of this book. First, the book is just a collection of questions that can be found on the internet by searching "practice iassc lssbb questions," or something similar. Second, the answers for each question are written literally right after the question, which is a bit useless if you're trying to study for the exam (I had to manually write down the answers on a separate sheet of paper and white-out the answers under each question). Third, I cannot trust the credibility of the answer key. There are some answers that are clearly wrong, yet the answer key says otherwise. Thus, it makes me wonder for the questions that I got wrong: did I actually get it wrong or is the answer key wrong? This should not be something I have to wonder.Save yourself a couple bucks and do not purchase this

Will be using to prepare for vertification.

I will be buying more in the very near future...

Only basic questions are provided in this guide. I was expecting some calculation based or formula based questions and they are not there.Another thing which I didn’t like is , the correct answers are given just after questions, means if I want to check my knowledge, I can’t ,

The book provides the answers but no explanations. Pretty useless if you do not get why you pick the wrong answer. Moreover I doubt some answers are correct and accurate, for example question # 59 refers to a chart/table that is not in the book.I wrote to the author to get explanations I hope he replies.

It is not a book - merely a pamphlet with 1 set of questions in it. Certainly doesn't warrant parcel post or a price in excess of £5. The printing is all in black and white and questions refer to red line.

A bit short. But is only a guide. Question and answer book. Seems quite useful

It is just a copy of many questions those are available on internet also. Questions and answers are given but no explanation is available. It is not worth with the price. Useless.
